The attempts to prevent supporters of the Maccabi football team are labelled antisemitic because they are directed at Jewish people; should it have been a muslim team then it would probably have been labelled Islamophobic.
The point is, no-one should be banned because of their country or faith; that is discrimination, and the fact that the West Midland Police force constructed and created false evidence, also hiding reports concerning Maccabi fans to support their case for banning, is shameful. It has been claimed it was done done in the cause of 'communality', to protect the residents, but in that case the Palestinian protests outside the stadium should also have been prevented.
