believe in God, believe in no god, and then maybe find agnosticism

I know what you mean--there's a great relief to ''come out!"

There's way better things to talk about than atheism, and I say this as an atheist.
It's like talking about all the TV shows I'm not watching now that I've given up on TV.
If the world weren't overrun by the socially communicable mental illness of religion we wouldn't even need the word "atheism" in our language.
It's like making a word for all non birds, like "pounders" because we move around by walking on the ground, but that would exclude fish and marine mammals, so maybe a random nonsense word like "navians" so now every time I refer to any "not bird" animal I have to emphasize the point by using the navian descriptor.
The word atheist is stupid since atheism is the default natural condition and requires years of mental conditioning against your natural instincts to correct your mind sufficiently to fit in with religious culture. The tag atheist emphasizes how we aren't part of the "normal" as defined by the abnormal theist in our delusional society which has suffered from this social/mental illness for thousands of years.

I don't feel a need for community. I know what I believe. Don't need reinforcement from others.

Prattle away. You are amongst realists, unblinded by dogma and superstition.
We only believe in the tooth fairy!
