My dear, dear innocent.
Crusades.
The Crusades were to kill not only
pagans, and
Muslims but heretics, which were basically certain denominations of Christianity.
I
did get baptized, and confirmed in the United Church of Canada. I also attended a Catholic high school for four years, where I was forced to learn the history of your beloved religion, most of which I had already learnt in Sunday School, at Church. Unfortunately for your God, my eyes were opened and I was taught about Christians killing Christians because they were not 'true' Christians.
And in the end, Jesus was a Jew. The term Christianity did not enter the picture until close to 200 years after he died and rose. Correct me if I'm wrong, I haven't taken a religion class in over two years.
