Zeev, Hate takes many forms. Zigi's hate was so over the edge, it was ridiculous. Personally, I thought he was jerk. There are other forms of hatred which are less obvious, and more incidious. Hate cloaked in religious doctrine is the worst, an abomination, imo. I think we saw some of that here too but that is just my opinion.
To say we have handicapped children because of "sin", and make a comparison to "3 legged frogs", is disgusting. If one were to "grade" hate, that sentiment is worse than antisemitism but again, my opinion...
