Absolutely not, sorry but this made me laugh, I mean if I made a little group to "talk," it would just be like, "yeah so I don't believe and I don't want to believe." and basically that's it...lol
Do atheists have meetings or any type of association to tell each other what they don't believe in?
No. Atheism is not an organization. It's an individual system of reality.
I am a believer but I have atheists in my family.
Even my late incarnate atheist sister who lived to be 72 said, "On a bad day I am an atheist but on a really good day I am an agnostic (searching).
Atheism can be organised, hence there are a jungle of atheist websites, here's a smattering: http://atheistanalysis.com/top-10-atheist-websites-you-need-to-bookmark/
The more I read about atheism the more I choose to believe. Believing in God doesn't come easy to many, and maybe that's a good thing: Having to cultivate one's belief.
I could write more, but I hope this answer helps.
Atheism it seems is the absence of belief
Yes, well sort of. If you go on Facebook, you'll see groups/pages where there are atheists that are just debating and arguing about many things.
Atheism is a religion by itself. Atheists gathering just about amounts to it.
