I agree with Dubu on this one. I am an Atheist, pure and simple. I may not know what "it" is, but I know what "it" isn't.
I believe everyone should believe what they are comfortable with. To each their own. It does not matter what someone's belief or lack of belief is, if they're an asshat, they're an asshat, period. Just because they are an asshat for Jesus or an asshat for nothing at all, it doesn't change the fact.
In my opinion, if you try to -push- anything on someone, you're a douche. Agree to disagree and move on with your life.
