I like Religious debates, no hard feelings in ay of this.
On topic:
You're bringin up things that happened long ago. Granted, some things in the name of Christianity still exist, no debate on that. What my point is, is that the Crusades were hundreds of years ago. A rock was a weapon in those days, not to mention crude medical practices, and what we would call a warped frame of mind. But it's quite funny some of these Muslim societies still live by ancient laws, that in most eyes are quite crude and strict. Guess we can go in circles on this, but from the looks of things Christians aren't practicing "Holy Wars" on anything. It would be small pockets, but in comparison to large groups like in Muslim communities in the Middle East. Trust me when I say they hate you for being American, white and non-muslim.
My point be done, and for the record I actually am not a practicing Catholic, I just believe in the Big Man upstairs and His Son. There are somethings that can't be answered, and there's my huge reason behind my faith.
Merry Christmas and bah fuckin hum bug!
