Flags are meant to be a  symbol  under which people unite – but in many cases a flag can cause  division.   Emotions run high when it comes to patriotism so it is not  surprising  that attempts to change a flag – or to fly a flag which  identifies a  minority of the members of a nation, can cause animosity.   This list  looks at 10 flags that are controversial.
 
The Rainbow flag or Pride flag of the  LGBT community (also known  as the gay pride  flag) is a  symbol of lesbian, gay, bisexual, and transgender  (LGBT) pride and LGBT  social movements  in use since  the 1970s. The colors  reflect  the diversity of the LGBT community, and the flag is often used  as a  symbol of gay pride in LGBT rights marches. It originated in the  United  States, but is now used worldwide. Designed by San Francisco artist Gilbert Baker in  1978, the  design has undergone several revisions to first remove then  re-add  colors due to widely available fabrics. As of 2008, the most  common  variant consists of six stripes, with the colors red, orange,  yellow,  green, blue, and violet. The flag is commonly flown  horizontally, with  the red stripe on top, as the colors would appear in a  natural rainbow.   
  

In  2007 in Angus, one of the 32 local government council areas of   Scotland,  the Angus Council decided to scrap the Saltire (the flag of Scotland) and replace it with a   new Angus flag. This move led to public outcry across Scotland with   more than 7,000 people signing a petition opposing the council’s move,   leading to a compromise whereby the Angus flag would not replace but be   flown alongside the Saltire on Council buildings. The new flag was   criticized as a waste of time and money, as well as a politically   motivated move. The design consists of four quarters containing a   crowned lion passant, a cinquefoil, a checked strip crossed with buckled   belt and a depiction of the heart of Robert the Bruce to represent the   four ancient earldoms of Angus.    
 
8 The Sun of Vergina Flag
 
On  August 11, 1992, the newly-independent Republic  of Macedonia adopted a new flag to replace  the old Communist  “red star” insignia. The flag depicted a stylized  yellow sun centered  on a red field with eight main and eight secondary  rays emanating from  the sun, tapering to a point. This ancient symbol  was known as the  Vergina Sun or Vergina Star, named after the Greek town  where it had  been discovered in archaeological excavations of the  ancient Macedonian  city of Aigai. It had also been adopted by many in  the then Socialist  Republic of Macedonia to symbolize historical  connections between that  country and ancient Macedon and had been  paraded in demonstrations by  ethnic Macedonians at home and abroad. 
The flag, the new state’s  constitution and its name all became the  focus of a bitter dispute  between the two countries, during which Greece  imposed an economic  blockade on the Republic from February 1994. In  July 1995, Greece  lodged a request with the World  Intellectual Property Organization (WIPO) for  exclusive  copyright to the Vergina Sun. Greek objections also prevented  the flag  from being flown at the United Nations Headquarters building in  New  York. The blockade was lifted in October 1995 when an agreement was   reached to change the flag, modify the constitution and resolve the   naming dispute through United Nations-sponsored negotiations.
 
7 The Pre-Islamic Revolution Iranian Flag
 
Like  the country’s current flag, the former one contains horizontal  bands of  green, white and red, but the emblem in the middle contains a  lion,  sun and sword, rather than the four crescents and sword introduced  by  the Islamic regime in 1980. Recently, the appearance of the  pre-Islamic  Revolution Iranian flag at U.S. rallies against the  re-election of  President Mahmoud Ahmadinejad has stirred tension between  two  generations of protesters.  While they all came out to express   solidarity with protesters in Iran,  each group views the flag very   differently.  Supporters of Iran’s deposed shah often bring out the flag   at demonstrations, and some would be happy to see a constitutional   monarchy restored in Iran or a secular democracy with no royal   figurehead. Younger protesters do not want to give Iran’s rulers any   excuse to accuse them of links to a movement that seeks to overthrow the   current regime, and often plead with older protesters to put away  their  flags. 
 
6  Japan’s Rising Sun Flag
 
The  Rising Sun Flag is the military flag of Japan. It was used as the   ensign of the Imperial Japanese Navy and the war flag of the Imperial   Japanese Army until the end of World War II. It is also presently the   ensign of the Japan Maritime Self-Defense Force and the war flag of the   Japan Ground Self-Defense Force. It is also waved during the Japanese   New Year and in sporting events. The design is similar to the flag of   Japan in that it has a red circle close to the middle signifying the   sun, the difference being the addition of extra sun rays (16 for the   ensign) exemplifying the name of Japan as “The Land of the Rising Sun”.   The flag was used in overseas actions from the Meiji period to World  War  II. When Japan was defeated in August 1945, the flag was banned by   Allied Occupation authorities. However with the re-establishment of a   Self-Defense Force the flag was re-adopted in 1954. The flag with 16   rays is today the ensign of the Maritime Self-Defense Force while the   Ground Self-Defense Force uses an 8 ray version. This flag is often   considered offensive in countries which were victims of Japanese   aggression, particularly China and Korea, where it is considered as a   symbol of Japanese imperialism.

The  Patriotes flag is a politically charged symbol often used by  hardline  nationalists in Quebec. It was used by the Patriote movement in  Lower  Canada (present-day Quebec) between 1832 and 1838. It is highly  similar  to the civil flag of the German bundesland of North  Rhine-Westphalia.  Some theories about its origins pretend that the color  green was  adopted to represent the Irish of Lower Canada, the color  white for the  “French Canadians” and red the English of the territory.  Some also say  that the tricolor style was inspired by the French  tricolor, symbol of  the French Revolution that inspired the Patriotes.  It became the  national flag of the Republic of Lower Canada at the Declaration of Independence of Lower  Canada in  1838.
Nowadays, it is used by contemporary Quebec independence  supporters  as a symbol of their movement and ideal. As such, it serves a  purpose  similar to the Estelada flags, symbols of the Catalan  independence  movement. It is often seen in crowds at Quebec National  Day concerts and  gatherings and was featured at the voting day assembly  of YES  supporters of the 1995 Quebec referendum on independence. 
 

The  Flag of Europe is the flag and emblem of the European Union (EU)  and  Council of Europe (CoE.) It consists of a circle of 12 golden stars  on a  blue background. The blue represents the west, the number of stars   represents completeness, while their position in a circle represents   unity. The stars do not vary according to the members of either   organization as they are intended to represent all the peoples of   Europe, even those outside European   integration. 
In 1985 the EU, which was then the European  Economic Community (EEC),  adopted it as its own flag (having had no  flag of its own before) at  the initiative of the European Parliament.  The flag is not mentioned in  the EU’s treaties, its incorporation being  dropped along with the  European Constitution, but it is formally  adopted in law. Despite it  being the flag of two separate  organizations, it is often more  associated with the EU due to the EU’s  higher profile and heavy usage of  the emblem. The flag has also been  used to represent Europe in sporting  events and as a pro-democracy  banner outside the Union. Euroscepticism,  a general term for opposition  to the European Union or the process of  European integration, however,  makes its use controversial in some  cases. 
 

On  January 21st, 2008, a new flag was confirmed by the Iraqi  parliament.  In this current version, the three stars were removed, while  the Takbir  (the words Allaahu Akbar, or “God is Great”) was left  written in green  Kufic script. The flag is controversial, as some Iraqis  refuse to  accept the legitimacy of a government whilst foreign troops  remain  active in Iraq. Some Sunni tribal leaders took offense at the  purging  of the stars, a symbol of the nation’s former Sunni regime.  However, as  of April 2009, Anbar province raise the new Iraqi flag as  evident on  the official site of Anbar province. The New York Times  reports that  the flag design recently imposed is designed to be  temporary and  mentions that Iraqis have “expressed varying opinions  about the new  flag.”
 

The  Confederate battle flag, also called the Southern Cross, Stars  and  Bars, Dixie Flag, or The Rebel Flag, has been described variously as  a  proud emblem of Southern heritage and as a shameful reminder of  slavery  and segregation. In the past, several Southern states flew the   Confederate battle flag along with the U.S. and state flags over their   statehouses. Others incorporated the controversial symbol into the   design of their state flags. The display of the Confederate flag remains   a highly controversial and emotional topic, generally because of   disagreement over the nature of its symbolism. As a result of these   varying perceptions, there have been a number of political controversies   surrounding the use of the Confederate flag in Southern state flags,  at  sporting events, at Southern universities, and on public buildings. 
According  to Civil War historian and native Southerner Shelby Foote,  the flag  traditionally represented the South’s resistance to Northern  political  dominance; it became racially charged during the Civil Rights  Movement  of the 1950s and 1960s, when fighting against desegregation  suddenly  became the focal point of that resistance. 
 

Also  called the Stars and Stripes, Old Glory, and The Star-Spangled  Banner,  the flag features fifty stars, representing the fifty states,  and  thirteen stripes, which represent the original thirteen colonies  that  rebelled against the British crown and became the first states in  the  Union.
The American flag is to some a symbol of the freedom, liberty  and  opportunity found in the USA, while to others it represents  America’s  military presence around the world or economic dominance.  While it is  not uncommon to see news footage of the American flag being  burned in  protest in the Middle East, it is also sometimes burnt in  protest within  the country. The United States Supreme Court has ruled  that, due to the  First Amendment to the United States Constitution, it  is  unconstitutional for a government (whether federal, state, or   municipality) to prohibit the desecration of a flag, due to its status   as “symbolic speech.” 
In my opinion, the modern era of  multiculturalism in America has  brought with it a lack of appreciation  for the value of  American  symbols. America’s earliest generations of  immigrants actively  assimilated into American culture and appreciated  the liberty they were  afforded that was often not part of the cultures  they left behind.
