Your last sentence Rosie51 is very pertinent and perceptive. I think I understand what you are saying in this discussion. That the crime is actually being Jewish, before a Jew even opens their mouth or engages in any untoward physical activity. Being Jewish attracts hostility, always has done, and Anniebach is right, always will around the entire world.
I am educated and close enough to the issue, to know in a small way, that being Jewish comes with the harsh realisation that antipathy towards you will exist for no reason at all. It is deep-seated and inexplicable.
I accept that the Maccabi Tel Aviv fans didn't exactly help themselves in the Amsterdam situation. But Rosie51 is right to say that it is impossible to ascertain the correct timeline of the incidents because none of us has that information. And anyway, how can anyone put an finger on exactly when insidious thoughts to stage an attack are being planned by either side? The pro-Palestinian campaigners had been protesting about the Jewish team participating in the matches for quite some time. Their animosity was already evident and building.
The chants about the children were inexcusable, and I agree with Wyllow3 that they caused embarrassment to peaceful citizens in Amsterdam. That is not a clever way to gain support for the Jewish cause. But support them one must, not just because of the WW2 context, but because they are eternally and universally persecuted just for being Jewish, and that, in my opinion, is out of order.
