Jesus was not "jew". Some "jews" lived in Judea at some point during the Biblical times, and based on this the tribe was called Judea for a while, over a thousand years later. Majority of the residents in Judea in Biblical times like them were not of the tribe of Judah.
In the 1800s they changed "Judah" in the Bible to "Jew," and associated Judea with it in the media.
That's why you think Jesus was a Jew.
In the Bible, the tribe we know today as "jews" were called Pharisees. Pharisees studied the Talmud and called it the Torah, still do, but the Talmud is in fact a system for disobeying the Torah.
So stop it with this nonsense that Jesus was a Jew.
