If Jesus did exist and the story is true, he was born to Jewish parents but turned away from Judaism sometime before we catch up with him again in his early 30s. He declared many Jewish laws as moot and since Reform Judaism didn't exist for another 1900 years or so, he was no longer MOT (member of the tribe).

What is a trumpanzee?

Yeah, that's because they are so, so uneducated. He probably has no clue about that either.

That is one of the great ways to press their hypocrisy button. Another is to say, Yes I hate Sharia law, in fact, I hate all Abrahanic law.

Jesus was born a Jew, he lived his life a Jew and he died a Jew. So the story goes. It is all contingent on whether he even existed or not.

Then shouldn't it be Jesus Christner, or Christberg, or Christstein? Fine. Whatever. He's a Jew. At least he's not a Mexican!!!

Are there that many people who seriously don't realize that Jesus was Jewish?

Well, that's because they're fucking stupid morons. What do you expect?
