The Antwerp Jewish community has a rather ambivalent stance on the presence of Muslim immigrants. On the one hand it fears (rightly) a Jihad, yet it continues to oppose the Flemish Bloc, which is the one single political party that has the guts to oppose the liberal multiculturalist agenda (and is vilified by the other parties with the usual "nazi" and "fascist" epithets for doing that).
At one occasion a Flemish Bloc senator doubted the correctness of the 6Meg figure of Holocaust victims. The Flemish consitution doesn't contain the equivalent of the First Amendment, and "holocaust denial" is a criminal offence since 1995, "thanks" to Jewish lobbying. This event probably shaped the fear of the Jewish community to embrace the Flemish Bloc as an ally against Islam immigration.
IMHO this is a foolish stance. Even if the Holocaust law (which I also abhor, since it criminalizes free speech) is a bargaining chip which the Jewish community might need to pay, it would be a very small price to pay for real safety from Muslim terrorism and attacks. I think the source (Jewsweek) is also biased against the Flemish Bloc as the writer expressly supports multiculturalism and uses the "neo-Fascist" slander. There are other voices. Today I read an article by Prof. Dr. Henri Rosenberg in "Faxkrant 't Scheldt" (fax-newsletter) stating
"Jews who until now opposed the Flemish Bloc, because that's what they were supposed to, are much less negative and the step to pro-Bloc becomes increasingly small. Support for the Bloc becomes discussable in Jewish circles, and is effectively discussed"
