ATTENTION: All Atheists!!!?

Religion is a cultural thing. But it gives people hope. You have less proof that there isn't a god than there is. I'm a former atheist, but now an agnostic. Why would you strive to take away hope, make immature comments, and destroy the morale of over 98% of the world population? I believe that you have moral values, but religion is the foundation of a democratic society and a stable society, at that. Look in the past. Everytime someone tried to take religion away from people (Nazi Germany, USSR, etc.) it has destroyed the society. If you're an anarchist, fine. Then it makes complete sense. But why do you have to be so immature about it? There is no concrete proof that there is a God, and no concrete proof that there isn't. There's a difference between blindly following religion (which not many people do anymore, mind you) and thinking for yourself. There would be a universal sense of egomania if we all thought there was no God. Tell me: What started the big bang; what sparked life?
