To the contrary, Atheists and Agnostics are ignorant idiots. They go to hell as well.
Personally I'm agnostic and in today's day and age I don't see how someone could be anything else (well, except for scientists who tend to er on the side of athiesm).
I'm agnostic, and not athiest, because I believe something must have initiated the big bang and I'd also like to think theres is more to life than what we just see in day to day life but ultimately, to genuinely believe something, there needs to be reasonable proof and evidence and until that happens I'll remain open minded yet skeptical.
Religion is purely the product of the culture you were influenced by when growing up and is not objective. When civilisation arises different cultures will arise as well and religion is often a component of that in trying to explain the world around that culture and also as a guideline for societal values.
