As a Jewish fan, it really irritates me every time this debate comes up, and Baddiel can fudge right off.
The word yid is not racist. It's just a word. It doesn't have some sort of curse around it that makes an angel die every time somebody says it. What is racist was the meaning of the word when used to be offensive towards Jewish people. That doesn't mean that the meaning of the word cannot change and it cannot be used for something else. For all we know, there could be some tribe in Africa who have the word "yid" as part of their language and it translates into "flower" or something, now if they talk about "yids" are they being racist? They probably don't even know what Judaism is! If I ask you to describe the night sky, you'd probably say "black". If I asked you to describe John Terry, you'd probably say "cunt". Are either of those words racist? No, because they're not being used in a racist context. But I asked you to describe a particular person of African heritage and you put those words together and called them a "black cunt", then that is being racist, because you're using the fact that they are black as a negative. But if I THEN asked you to name the area between Wolverhampton and Birmingham, the words "black cunt" would also come out of your mouth, but there is no mention of race whatsoever.
My point is, it's all about context. Something is only racist if it is used specifically to highlight somebody's race. When Spurs fans sing about yids, we are not thinking about Jews, religion or race, they are thinking about football and that is how it should be interpreted. Yes, there are a few tossers who support Chelsea/West Ham or whoever that sing songs about Spurs on their way to Auschwitz, but it seems right now that the only people bringing racism into the equation are people like Baddiel that won't let things move on. If he wants to be such a Language Nazi (scuse the irony) and insist that every word's original meaning is the only true one, I insist that he leaves all his money on a slope next to a river, tries to hit cricket balls with flying animals that live in caves and does his DIY by smashing the plates that grow on the end of his fingers into a wall.
