No need to apologise trisher. I knew you meant it ironically. I despair that people read and believe labels without thinking about the issues and researching them.
FWIW My own personal view is that I don't believe for one moment that Corbyn is anti-Semitic. Nevertheless, certain sections of the Labour Party are strongly associated with pro-Palestine movements for very worthy reasons. Some Jewish spokespeople claim anti-Semiticism and anti-Zionism are the same, although others don't. Unfortunately, for some of those supporting Palestine, anti-Zionism and anti-Semiticism have become blurred. I think there are elements of anti-Semiticism amongst some supporters of Palestine and critics of the Israeli state. I don't know whether it's been exaggerated or not or whether Corbyn critics have used it as a weapon to attack him (maybe both, but I don't know for sure).
I do think that Corbyn has been slow to react to the attacks and to take action where necessary. He's been politically naïve, but I still don't believe that he himself is anti-Semitic.
It saddens me that the media can go on the attack and quote a couple of isolated incidents without evaluating the whole picture. The public then picks up on the attacks to support their own beliefs and the whole thing escalates. That's how propaganda works.
PS. I have issues with Corbyn, but they're nothing to do with anti-Semitism. Unfortunately, it rarely seems possible to discuss serious issues because it's impossible to get beyond the anti-Semitic, Communist label.
All my own very humble opinion.
