Jews Are Sumerians, Who Were "Aryans"
Just because two ethnicities are in the same language group doesn't mean they are genetically related. With all the evidence from other ethnicities, there's no excuse for believing that Jews are Semites. Besides, the Jewish character is obviously completely different from the Arab character.
The Bible, with its two completely different attitudes about Ishmael, the Father of the Arabs, gives a clue to what must have happened. Just like Africans who speak a White language now, the ancient Hebrews were captured and enslaved by Semitic tribes and forced to adopt their Masters' language.
