Ok so these few in contrast to the thousands in Muslim countries. I just seems that you have more of a problem with Christianity specifically. I also seems like you don't have so much of a problem with how gays are treated by any other religious systems, namely Islam.
I suppose it stands to reason. You didn't reference it specifically, but I assume you were born here. Chances are you were reared in a home with some sort of Christian background. Even if you were reared in an atheist home, 99.9% of atheists come from Christian backgrounds as well. I did the atheist thing for a while. It just didn't do it for me. Funny thing is, in all those years, I never ever met an atheist that was once Buddhist or Muslim....weird, huh.
