I see the same thing here although I have no idea about the personal faith of those involved and don't really care. But there are a few who use every opportunity to vilify Christianity and look down the nose at the "idiots" who profess faith in it. Oddly enough, no such proscription against Islam, Buddhism or Judaism. Odd isn't it?
Well christianity is talked about most because it's so big and popular in the West. Other mythologies are just as ridiculous to nonbelievers as a bloodstained cross one.
Is there some reason why we shouldn't vilify christianity? It's a hate group and it's teachings even speak strongly against nonbelievers and other faiths. You reap what you sow.
