I am now an agnostic. ShadowBrain, Glorb, The Chef, Lizard Dude...I'm joining the "atheist/agnostic team," so to speak.
I cannot bring myself to suspend my reason any longer. Faith is nice to have until it interferes with reality. There's simply not enough evidence to prove God exists. Does that mean God doesn't exist? Not in my opinion, but I'm tired of putting my faith in (like Luigison said) a 2,000-year-old book/religious authority. Religion breeds a lot of hate and I'm tired of being associated with it. I just want to love without dogma getting in the way.
Until something or someone proves me otherwise, I am going to remain skeptical about God's existence. I'm not going to be militant about my agnosticism, but I will (respectively) disagree with men/women of faith.
Now...someone tell me I'm going to hell! :)
