A British/Scottish football club who think they are Irish. Since 1888 it has been sectarian by its nature. They hate everything non catholic most notably by the failure to offer Jock Stein a place on its board and its fans hatred to clubs whose fans and players are non catholic.
Its support and players actively support Irish terrorism and sing songs of hate against everything British including the british armed services.

Like the Catholic Church, Celtic has covered up sexual abuse of young boys for its own preservation most notably by its greatest manager Jock Stein and captain Billy McNeil who described it as an open secret. The fans of the club are racist,intolerant and sectarian and bring nothing but shame on law abiding Scots. The mocking of the 9/11 planes gesture to Claudio Reya was a disgrace as was the mocking of the Ibrox Disaster and the death of Davie Cooper which goes beyond any sporting rivalry and death threats to the spaniard Nacho Novo and his family. When Mark Walters came to play at Ibrox his first visit to Parkhead was marred by bananas being flung at him by Celtic fans. More recently the racist taunts of El hadji Diouf another example of Celtic fans intolerance to people of colour. Both current and former players are ofter seen at IRA Fundraisers and Rebel Nights singing songs of hate and sectarianism.

Glasgow Celtic FC: Football/Soccer team supported by mainly Scottish catholics (with or without irish decent, although commonly with) and every plastic paddy around the globe. Fans of this team often sing pro IRA songs. Now Pro- Irish Republican Songs are not really offensive to most like minded Rangers fans and indeed non rangers/celtic fans in scotland, however, pro -IRA/terrorist stuff is!!!!
Glasgow Celtic FC: founded by an irish monk in glasgow to help support poor irish immigrants in 1888.
GCFC: claim to be a scottish side however youd be hard pushed to find any of their fans flying the blue and white saltire at their stadium (the scottish flag for those of you who are thick or just american) instead it is a sea of tricolours (rep of ireland flags) and other irish flags. It's particuarly strange and I suppose sad that a sizeable portion of these guys have little or no irish blood in them, being scottish catholics of scottish blood. Ok most catholics in scotland now are of irish decent but it wasnt always that way. (see definitions of Scotland by bigmanofscotland for more info on this)
What it is I am saying is that it is ok to fly the odd irish flag if u happen to be on...

A scummy football team from Glasgow's East End who cheat their way through every game, and, in season 07/08, managed to cheat their way to the SPL title by dodgy decisions by referees and linesmen. Also every Celtic fan believes that somehow they are related to Ireland and that there were about 10,000,000 Celtic fans in Seville when they reached the UEFA Cup Final in 2003. More proof that Celtic FC are scum is that their own manager cast a blind eye upon a paedophile ring that was operating inside the club (Big Jock Knew).

Celtic FC are the most famous football club in Scotland with the largest following and the biggest football stadium in the country with a 60,800 capacity. They are Scotland's wealthiest football club and the first British team to win the European Cup. The club has always been a non-sectarian institution who are open to all.

Many Celtic supporters are of Irish Catholic origin and the club itself was formed in 1888 to provide funds for Irish immigrants in the late 19th century. This is why the team's colours are green and white.

Celtic fans have an excellent reputation throughout the world for good sporting behavior and were awarded the FIFA and UEFA Fair Play Awards in 2003 for their excellent conduct at the UEFA Cup Final in Seville.

Celtic form one half of the "Old Firm", the other half being Glasgow Rangers (a club which excluded all Catholics for 116 years before being threatened with expulsion from European competition if they did not end their sectarian signing policy).

Celtic are quite simply the best supported football club in the world. A Scottish based football team founded by Irish Marist Brothers to raise money to feed the poor immigrants who fled Ireland in the 1800's from starvation and poverty.

Relations with rivals Glasgow Rangers became frosty after an influx of bigoted shipyard workers from Belfast identified with the blue half of glasgow and spread sectarian filth through the west of Scotland, up to and including sectarian employment policies.

Polar opposite to Glasgow Rangers. Celtic fans were awarded with FIFA and UEFA awards, while nazi saluting Rangers fans (who masquerade as Englishmen)are awarded with UEFA charges.

In responce to wellbhoys entry I would like to say that he is jealous of the talent of the motherwell team after celtics unfortunate defeat on the final day of the season a few years ago which gifted the SPL title to rangers. I would like to state that well fans hate celtic as much as they hate rangers. I would also like to add that it is a very hypocritical (not that you will understand the word) thing to say call well fans biggots when you are refering to rangers fans as huns and motherwell fans as spineless. Wellbhoys comments on things motherwell fans like are also innapropriate as terry butcher managed motherwell, davie cooper was one of the greatest players ever to grace the claret and amber jersey and finally the union jack is the flag of great britain and only biggoted rangers fans asocciate themselves with it like the biggoted celtic fans asociate themselves with the republic of ireland.
