I thought a lot of atheists prided themselves on familiarity with holy books?
Anyone who has read the Bible and the Koran would be able to tell that when the god written of therein speaks, it is not the same entity whatsoever and it is merely “Muhammad” that claims it is.
I have read both, and the jealous, angry, mercurial, vengeful God of the Old Testament most certainly has the same traits as the Muslim God.
