I think my issue goes beyond addiction and is more about labels. I don't like them. I hate telling people I am an "atheist". So often I get responses like: "So, you think we just came from nothing?" and immediately it is demonstrated that that person has a completely different view of that word.
Socialist, pacifist, conservative, Christian, alcoholic... people hear labels like this so differently.
If I lived in the old west I would cringe hearing people being called "Lungers". I would be the one saying: "Shut up! They have tuberculosis!" lol. And I'd probably be shot for it.
Since there are almost no true Atheists, you could go for the truth and say ignostic/agnostic,
you don't know (and you don't care [ignostic]) - many people use the term Atheist wrong,
an Atheist would believe with a determination behind it that there is no God whatsoever, just like a Christian would believe in Jehova - for some reason, Christians can deal easier with agnosticism, if you say "there is a chance your God exists, I just don't care either way" it's usually fine.
How can anyone be a determined believer in that, truly? Just because God lets people suffer?
But how do you know the suffering is not part of the learning experience?
Our minds are so small and the universe is so ridiculously huge, if there was something as a creature resembling a God, we would simply not comprehend it.
Atheism is a statement in itself: "I believe your God(or any God) does not exist". This can be hurtful for certain believers, you metaphorically spit on their God by saying it, or so they will interpret it. Just say agnostic, it's probably closer to the truth.
You don't know there is no God, so don't pretend you do know that all the lives of believers are in worship of nothing. It hurts them, don't state it like that.
It's like an attack for them, I think you can understand that. I would, personally refrain from using that word. I've been using agnostic for years, and I've never had a problem with fanatics, because I can tell each and every one "Yeah, you might be correct"
I'm not touching American definitions of "Socialist", "Conservative", etc with a 20-foot-pole.
