So, the Pope's in hot water for claiming that Muslims used violence to spread their religion during the early days of their faith. What a strange thing to say.
In their early days, all religions have to use violence, just to avoid getting their butts kicked. If they want to spread, it is completely necessary to use violence. If you read the Old Testament, it seems that the early Jews did little other than run around and kill people of competing faith.
Anyway, it is a little tasteless to point out Islam's violent proclivities without pointing out that it's as common as dishwater. He is the Pope though, it's not as though he's going to start ragging on Christianity for being violent.
In the words of Stephen Colbert, don't mess with this guy. You know how powerful popes are, just imagine how powerful a Nazi Pope must be.
