The second thing you need to know is the importance of Mohammed the prophet. His behaviour is an example to all Muslims and cannot be criticized. Now, if Mohammed had been a man of peace, let us say like Ghandi and Mother Theresa wrapped in one, there would be no problem. But Mohammed was a warlord, a mass murderer, a pedophile, and had several marriages – at the same time. Islamic tradition tells us how he fought in battles, how he had his enemies murdered and even had prisoners of war executed. Mohammed himself slaughtered the Jewish tribe of Banu Qurayza.
