I think people need to recognise that poor Greenstein is very ill. His demons have got him in such a vice-like grip that he can't stop spouting filth about his own people. He's not even above attacking innocent bystanders at public meetings. People who support him aren't doing him any favours. They're simply helping to make his illness worse. The man needs psychiatric help, not paeans of praise from Jew-baiting thugs.
