Christianity has been full of violence right up till the last century - just think about WW1 and 2. Prior to that the history of Christian was full of blood, the Crusades, etc.
Islam still seems to be in its Dark Ages but somehow I don't think it will be centuries before Islam 'grows up'.
I thought this was the "positive statements about Islam thread", not the "Make the dumbest statement you can possibly make" thread.
If Islam "grows up", it'll be because outsiders force it to grow up, not because it has the capacity within itself to do so. Islam is the retarded kid of world religions.
