That is an absurd statement. I am an American Jew. I am not nor are any of my extended family marxist. I have many Jewish friends. None are marxist, none are atheist and none hate Christians. Quite the contrary. We respect and honor true Christians. Good people. Most of us are conservatives. Don't fall for the media caricature of Jews.
Not all Jews of course, but many who did come to this country were Bundists, who hate Israel and Zionism.

Thank you for the clarification and I am praying for the Peace of Jerusalem. It is definitely going to get rough.
