something interesting on the news. They did a store about hate literature in Saudi Arabia, with an example books that teach all religions other than Islam are false. Well, if they did not teach that, then, as Sam Harris would put it they would be intellectually bankrupt. The Koran makes claims that contradict those of the Athanasian Creed/Trinity. Both the Athanasian Creed and the Trinity cannot be correct.
(The Koran has Jesus telling Allah that he never directed the people to worship him and his mother.)
Monotheism is intolerant since if only one deity exists, all the other reputed deities are either fake or demons.
