I just don't understand the "Jewish disconnect" and their seeming blindness to the liberal left's obvious catering to the terrorists, prejudice against Israel and outright coddling of Palestinian terrorists in particular. I've heard it explained, but it still don't make sense. It looks like suicide and self-hatred.
I also think, that as people who are discriminated against all over the world, they have a natural tendency to gravitate towards policies that promise "non-discrimination." Many of the Jews who came to the US fleeing the holocaust had seen the problems created with the Nazi propaganda, and fear the racism.
