You obviously need to look up the phrase reading comprehension. I did not state that they were extremist now...Just that the logic and teachings were the beginning steps in that direction. Just as I pointed out that Islam has not always been like that either. Suicide bombings did not exist 50 years ago. Look up the history of Wahhabi'ism to see where Extremist Islam began.
Christianity has been the exact same way before (Dark Ages) and has had many followers claiming to be the most devout Christians doing the most abhorrent things throughout history. Rocket pig gave you some examples already.
My point is the religious ideas put forth about gay marriage, stem cell research, creationism as an actual science to be taught in school, etc are all the first steps in that direction.
