From what I can see of their fans behaviour I don't think they deserve to be banned. They've clearly been involved in some incidents over the last few years, but I don't think they've done enough to merit their away fans being banned from attending matches. The Amsterdam events seem to be the main thing and it's clearly very debatable how much of the blame can be attributed to Tel Aviv fans in this. Some of their fans supporting Israel's actions in Palestine is absolutely not a reason for them to not be allowed away fans at matches.
Having said that, If WMP/safety groups say they there's too much of a risk to people's safety for their fans to attend then I'm willing to bow to their greater knowledge of the situation and concede it's probably the correct decision regardless of whether the fans actually deserve to be banned or not.
