That's not fair! Yes, there are many references in the Koran to crimes against humanity (I saw that book "Sword of the Prophet" in the Conservative Bookshop) but there are in the Bible too. The exploits of King David need a strong stomach to read.
It's interesting that when the crusaders captured Jerusalem they put every non-Christain to the sword, but when Saladin recaptured it, he ordered that the Christians go unmolested.
I judge people as people, by their actions. I don't care what religion they believe in. I've known some good muslims and some bad muslims, just like I've known some good Christians and bad Christians
