I'm cynical
Muslims and Christians believe totally different things
Technically a "good Muslim" is one who hates the infidel. The Koran says that. The Koran encourages Muslims to even kill the infidel. So how are the 2 going to get along when one group believes in murder and the other believes in turn the other cheek?
I don't trust any Muslim, quite frankly. True, i don't trust any human regardless of "religion" or philosophy, but whatever...
