You make it sound like you need to be religious to have a heart; or perhaps the other way around, that if you're not Christian, you're basically a talking zombie. I'm related to a number of atheists who are several times as virtuous as some of the most Christian people I know*.
Chupperson's comment was questioning if you think that people are too stupid to know right from wrong unless they have a priest tell them, not calling you stupid.
Large, personally religious edit:
*Actually, they're only claiming to be so religious. The main person I have in mind are pretty awful. Her hypocrisy is almost painful.
You can think whatever you want of me. Like I've said before, I have my own ideas of what God is like that sometimes contrast what the Bible says, or at least what everybody interprets it to say. If I'm terribly wrong, if a Theocracy is the only acceptable government, I'll suffer for thinking a democracy that supports minorities' rights instead of the majority's preference is best. If gay people really are the children of Satan, I'll suffer for the mistake that they're humans and the mistake that a kind man who happens to be attracted to other men is a better one than a man who rapes women and steals and kills for the heck of it.
But I've always been told that if I believe Christ died for mankind and have faith in our merciful God, I'll end up in the kingdom of Heaven eventually. If by some twist of fate I'm rewarded for not submitting to peer pressure and supporting a Christian-run country that cuts homosexuals off from basic rights, that'd be all right. I'm going to keep following my own heart and doing what I think the benevolent creator of the universe would like me to do.
