I read that article too but I think they are probably glossing over some events (and they do seem to be favouring the zionists), most likely the israeli party's "discussion" with the other table. I'd bet good money that that arose because of the (apparently prominently displayed) signs supporting Palestinian rights and they were probably not having some quiet discussion but more likely kicking off.

I'd be happy if this happened everywhere, all the time. Like the anti-apartheid boycott of South Africa, they need to be ostracised as much as possible from everything.
