I'm still trying to figure out anti-Israel Jews.
Just remember the 1,000-year-old joke: Put 12 Jews in a room, and you come out with 13 different opinions.
It's a cultural thing: Come up with totally new and unheard-of ideas and positions on anything, challenge ANYthing your parents and teachers believe, and maybe even play Socrates. Why do you think Jews make proportionally more medical and scientific discoveries than any other group?
Does the story of Moses and a golden calf mean anything to you?
