Iam64 There are indeed Muslim players in Israeli teams, both Israeli Arabs and Muslims from outside Israel. It's quite common for them to suffer anti-Muslim/Arab chanting/abuse, but little is done about it by the Israeli authorities.
I agree with you that not all Israelis should be damned for the behaviour of the Maccabi ultras, just as not every English person was damned when Millwall was considered one of the most racist and violent teams in Europe.
I think Whitewave is right about politics, although I'm not sure she's aware of the team's historic context. Maccabi Tel Aviv was founded in 1909, long before the state of Israel existed. It was founded as a Jewish club at a time when Palestine had an Arab majority, with a Star of David as its logo. After WW1, when the British controlled Palestine, Maccabi was still the only Jewish football team in the area of the Mandate. It was the strongest team in the area and became associated with Zionism and that link persists to this day.
