"Is Rotterdam one of the Dutch cities that have become a Muslim enclave?"
Much of this open anti-Semitism comes from non-Muslim Dutch. The nation has a very long history of anti-Semitism - see the article directly below the original post.
Aside from the old anti-Semitism, the new anti-Semitism is rampant in Holland with over 75% of the Dutch population believing, for example, that Israel is the greatest threat to world peace. Just like the old sort of anti-Semitism that deligitimised Jews before murdering them, the new anti-Semitism in Europe is doing the same with the collective Jew represented by Israel.
Good point. Although I thought about the Muslims since they have become entrenched in many Dutch cities and the article mentioed the "Hamas,Hamas" chanting.
You may be right about the open anti-Semitism coming from non-Muslim Dutch, but we have seen one too many stories from Europe (especially France) that goes out of its way not to mention that perpetrators are, in fact, Muslims. And considering Rotterdam is such a Muslim city, it would not surprise me if this were caused by Muslims.
This thing has been going on for a long time, before the Muslim influx, but seems to have gotten worse.
Most of the anti-semitic violence in Europe is being perpetrated by the Muslim invaders. Most Europeans are too genteel to openly say what they really think about Jews. That's what makes me think the soccer fans in question are Muslims.
In other words, make them non-persons and less than human, smear them so badly that no one will come to their aid, that people believe they deserve what they get...and then kill them. I understand now.
