Thank you. He certainly did make such videos which he claimed to be parody adding useful balance to the Israel/Palestine debate -- I think we would agree that this was not useful, but I don't believe his intentions were anti-Semitic.
He does (going on his online postings) regularly spout anti-semitic nonsense, but then he is a very troll like person. So it is hard to figure where his real beliefs lie - he often sounds serious, but then he may just be a serious troll.
(and, also, I suppose it is arguable his intentions [trolling or meaning it] are irrelevant because it still goes out there and communicates to people without being clearly ironic)
