Can I ask a sincere question? Why does atheism bother you? I mean, if you have your faith, nobody can take it from you. If your faith is true, nobody can change your mind. Why does someone else's bother you?
Personally, I disagree with this group. I think they're just plain stupid and silly, but what impact can they have on my faith? They can't take it from me.
In a personal sense I simply find them annoying. Their inherent arrogance, as well as them spending so much time and energy fighting against something they profess to not even believe in. In another sense, I think these types are a sign of what is to come in terms of religion becoming more marginalized in our society. They may seem extreme even to you right now. But their views could very well be mainstream and widely accepted in another generation.
Personally I find hard core aethiests and hard core religious people equally annoying. Anyone who is vociferous about the existence of a Supreme Being hasn't thought it through. There could be a God and there could not be a God, I am not amart enough to say. I have my own beliefs, but they are mine, and I have no desire to fost them on anyone else. And whatever some group of fringe religious zealots or anti religious zealots do is not going to afftect what I believe to be true.
I'll tell you one thing, however, God is not some old white guy with a beard who lives in the sky.
