Sorry I've forgotten about Yemen, and will ignore the rest of what you said, because I have said previously that there are a lot of different races have been intermingled with the Arabs because of the expansion of the land that is used by Arabs and because of the succession of generations and civilizations.

Israel is completely different issue than Arab world, the Arab do not believe in a country called Israel because they think it was built on an Arabic land called Palestine.

By the way, Arabs believe in the three religions, Christianity, Judaism and Islam.
