I’ll believe it when Jews turn on the Democrats....
Religious Jews vote Republican. Having Jewish ancestry doesn’t make you a practicing Jew, any more than having Christian ancestry makes you a practicing Christian.
Throughout the history of the Jewish people, there has always been a battle between the Jews who are faithful to the Jewish religion, and the assimilationed Jews. That’s what the story of Hanukkah was all about. It’s the religious Jews who keep the Jewish religion alive, and the assimilated Jews are like leaves falling off of a tree. The Jewish people are self-sustaining, because enough Jews pass on their beliefs to their children.
The more important question is will Christianity survive now that all the cultural institutions of the West that used to promote it now denigrate it?
