Arrogance and smug self-satisfaction.
Wanna know what has been really pissing me off lately? This argument for theism:
"I don't see how all of this could have happened without a creator."
Really? YOU can't see it, huh? Well, I suppose since YOU are so F*****G super intelligent and your enormous brain can't encompass it, it can't possibly be true? A fact cannot exist outside YOUR immensely extensive experience in this universe?
GODDAM it! Get your ego under control already! Just admit that you're fallible! Admit that there IS a possibility that there may not be a creator! You have not been right about everything in your life, so you are not an authority on reality! I fully admit I don't know everything, and I would NEVER claim to KNOW (with a capital "K-N-O-W" ) if there was a god or not.
It's amazing to me how most major religions teach humility in word, but not in practice.
Now, if you'd like to join us in the imperfect human race, I'd like to talk to you. Otherwise, you risk a verbal H-bomb from me.
P.S. Atheists who claim absolute knowledge on the subject irritate the crap out of me too.
