Were these expulsions collective punishments for the "attempted genocide by Arabs" you mention? I've never heard of such an attempt, would you please elaborate.
Lets rehash. You say; The vast majority of Arabs fled their homes. The Arab supremacists attempted genocide so the Jews committed violence in return and the Arabs hate the Jews because Jews are peaceful, and too weak to really dominate.(2) Hatred of Jews is based on many things - tribal competition, Muhammed's mass murders of Jews and saying like "the trees will say oh Muslim there is a Jew behind me, come kill him", etc., not to mention the Christian blood libel, etc. Often, though, hatred of Jews is merely based on the fact that Jews are an "other" who is too weak to really dominate. You notice that lots of other far larger groups, who have committed much worse actions, are not so hated. People don't hate powerful opponents... its counterproductive. They hate the small, peaceful, weak and meek, because it is easy to bully them.
But you do dominate. You're not living in refugee camps.
When you appear to believe your security and comfort to be more important than another's, it sounds really silly for you to call them supremacists. See what I'm saying?
When you said, "You notice that lots of other far larger groups have committed much worse actions" - to which actions were you referring? Much worse than what?
(by the way, Americans are not innocents, this is so and we criticize ourselves/government)
