''I've been waiting a year for you to prove jesus was a jew.''
Well, you must be blind.
I have posted referenced material in abundance, which describes genealogy, the evolution of a people, Hebrews, Israelites, the state and tribe of Judah, time and time again.
And what do do you do? Ignore all of it only to ask the question over and over. It's something a child would do.
