WTF? I really don't know where to start. I've read and re-read the OP and I'm lost as to wtf it is about. It seems to be yet another attempt by a theist to tell me what I don't believe and why I don't believe it.
Unless your (imaginary) atheist friends number in the thousands, have been randomly selected and you have developed a robust data gathering tool that has been vetted by a screening committee of experts, I would suggest that your limited anecdotal and experiential dataset is pure bullshit.
I thought I was an atheist because I'm angry at god (yeah, THAT makes sense). But I suppose now I'm an atheist because religion screwed everything up, so I guess I'm just angry at religion and I'm taking it out on god. WTSlave, I'm an atheist becase I spent decades meditating, thinking, studying, researching and questioning. At the end of that very long sojoun it was clear to me that based on the (lack) of evidence, there was no god. If she changes her mind and provides irrefutable evidence of her existence, I will believe.
Emotion had nothing to do with my atheism.
That, based on your very limited access to (imaginary) atheists, you would make definitive statements and assertions rather than posing a question or asking for atheist feedback strongly suggests that you are a delusional narcissist who wants the posters and lurkers on this site to think of you as a wise sage. Oh, and you love the sound of your own voice.
Next time ask a question. Handling it in the manner you did reveals your true intention.
