Check out the reaction of a Muslim woman:
Notice she says that no non-Muslim has ever entered the Kaaba, even though it was a pagan shrine until Muhammad conquered Mecca and strong-armed it from the polytheists. Apparently, Muslims have rewritten the history of the Kaaba in order to keep it holy in their minds.
Why such a violent response to a video about a stolen pagan temple? Idolatry, anyone?
