I have to be truthful and suggest that Arsenal fans are no more anti-semetic than most folk. It's an anti-Tottenham thing where Jews are cought in the crossfire. Spurs fans will throw back abuse about 'kebeb crunchers' but think nothing of getting a takeaway on the way home from the match. I have been to many a Spurs match, and again to be honest, the vast majority of fans are White Christian (sorry if that upsets, but I hope you know what I mean) people who don't give a stuff about Judaism..........all they care about is three points off the Gooners!
(I may have put this all wrong, but I didn't mean to offend....honest)
