It goes back to the 30's at least, when Jewish Spurs supporters faced physical racist attacks by opposing fans and got together to form the first football 'firm' in order to protect themselves at matches. Apparently, this was the first organised 'firm' in England and thus possibly the world (unless some Scots got there first) therefore meaning that the Jews invented another famous British export to go with fish n chips! It really annoys me that the authorities can't get their head round the fact that the term 'Yid' is similar to the term 'black'. If used as a negative, then it is racist, if not then it is simply descriptive. (For you non-Ashkenazi's out there - in the Yiddish language, 'Yid' means 'Jew' so the the Yiddish language is simply the 'Jewish language').
