Perhaps you're just saying things in a simplistic way, but saying that religion is the cause of most of humanity's problems is extremely simplistic. To me, Troyboy was right when he said that the unfortunate thing about Islam is that it is being used to justify the viciousness of Al Qaeda.

If you actually believe that religion is the cause of all humanity's problems, you should put away your textbooks and pickup the Bible or Koran and read them. If you're looking for support of evil actions then you're reading them like the Imams who support murder and the Pope's that supported the genocide of South America.
