If you are implying that their is some kind of symmetry of equivalence between Christianity and Islam, consider this. The early Christian church spread throughout the Roman Empire while it was still a savagely persecuted non-violent religion. Torture and execution could not stamp it out. (Later, of course, it became an established church in many areas.) Islam was spread by the sword from the very beginning. If the Muslims are so confident that their way is the truth, why do they kill any converts in their theocratic empire, forbid proselytizing by other religions, etc.? Atheists always like to depict all religions as basically the same. They aren't.
"Gee, how nice to know you have all the answers"
I'm always struck by how atheists "have all the answers." E.g. religion is "just superstition," "just psychology," etc. Something not tangible to an individual atheist's material senses doesn't count, even if that "something" moves millions of other people to live a certain way and do things which are not necessarily in their self-interest. "Just mass hysteria," I guess.
Or do you care?
No I dont.
