Agnostic is the very definition of not having made your mind up.
I was agnostic for years, as, really, I like the idea of there being a God. Of course, I also like the idea of there being a Gandalf and Batman.
Agnostics should just shut up and pay attention. Listen, really listen, and then think, really fucking think. And then become atheists.
I went the other way. I was an atheist first, but I thought about it long and hard and became agnostic. Purely based on my own perceptions. Not going to try to change anyone's belief systems though, everyone's got their own reasons for thinking the way they do.
I don't mind agnostics unless they start acting above the debate. 'Oh, neither side will know so it's pointless!' etc really pisses me off. Giving undue respect to religion and then being an uppity cunt at the same time. Disgusting.
But I don't think you're one of those so feel free.
