Meanwhile, the decades-long overwhelming support given to Israel and Zionism by Fundamentalists probably offends him even more. After all, "these people represent evil, genuine EVIL!!!"
That's an interesting question; how do far lefties like Dershowitz feel about the fact that the most ardent supporters of Israel in the US are evangelical Christians, who oppose him on almost all other issues.
Though I will say one thing for Dershowitz: I once heard him talking about judicial activism and he seemed to be somewhat reasonable on it. I can't remember which, but he said that either the Second Amendment clearly protects an individual right to own guns, or that he felt that the Roe v Wade decision had been improperly decided and that abortion should have been left to the states to decide. He may have said both, I'm not sure, but I'm sure that he said one of the two, and that's rare for a liberal law professor.
