What drives me bonkers in such conversations is the trying to decide on universals that will fit everyone. Umbrella terms. Like your story is always gonna be my story. Yeah. Makes me nuts.
You said you stopped believing. Shouldn't you have said, "I CHOSE to stop believing?" The former statement supports what I've been saying.
Yes, I actually did choose to stop believing. It was a very gradual process that eventually culminated in a single day.
I'll start with what I said earlier: I don't care what you call me, or even how I label myself. If you think the term agnostic better encapsulates my position, use it. If atheist, use that. It honestly doesn't matter. What matters is that I did break away from an abusive system, and in so doing, learned to think more critically in general. Hooray for me.
After I deliberately left Christianity, I played around with Paganism for a while. I simply didn't know how one lived without a god-being to worship, so I picked a female one the second time around. After that started seeming just bat-crap silly in a hurry, I went around for a long time calling myself an agnostic. But I think I defined it differently than anyone here has, so far. I was wrong, I guess, but it made sense to me at the time. It made the sense I needed it to make, for me.
I would say, "I believe there is
something out there, a being greater than humans, but I don't know its nature. I don't and can't know what it is. But I do think there's
something there. So, I have no religion, but I do believe in some kind of god." I was letting go of faith gradually, you see. I still needed something, even if I didn't have anything to call it.
Later, when I was finally willing to give even that little bit up, I called myself an atheist: "Now, I no longer believe in even the 'something greater.' There's nothing out there; it's just us, and the crap we make up to hurt each other with, and that's all. I'm an atheist. I no longer choose to believe in any gods. As far as I know, there are none. Fin."
I do consider I made a choice; a few choices. Maybe you don't know how hard it is to break away from faith itself. Maybe you do, I dunno. But maybe you'd be surprised at the sheer amount of crap you can make yourself swallow simply by telling yourself you have faith. Or telling yourself, when you have doubts, that it's just Satan, trying to deceive you. Can't be too careful; I've heard he's a tricky bastidge. If you can make yourself doubt that your own thoughts are coming from within your own head, what won't you believe?
At some point, there came a time when I said "enough. Just stop it."
And, I did. Call it whatever makes you happy. The label doesn't affect my reality.
