One other issue was that many atheists i've ran across in person tended to be arrogant SOBS. This is probably a poor selection since I probably ran across many more who were great, but didn't feel the need to force it down my throat.
I guess as a type of polarizing response, I had a disdain for atheism as for most theisms.
then coming to this website, I greatly enjoyed the debates on science, but reading the arrogant views of some atheists, it rewoke those feelings.
That's I guess it in a nut shell.
thanks for asking
I think a lot of us went through such a stage. Again, not that this means that you'll turn out to be an atheist, too, just that it's not that unusual.
For years I didn't give a whole lot of thought to the issue. That sounds strange now, but when you don't live in a very religious area, or have a religious family, or hang out on atheist or atheist-friendly websites, it's amazing how rarely it comes up. Even now, outside of my time on the internet, it rarely comes up.
Anyway, during most of that time if you had asked me, I probably would have described myself as agnostic. I didn't really know any atheists (at least, as far as I knew), and I had the impression that atheists were all crusaders who thought they knew it all. I patted myself on the back for being so open-minded.
But the truth is, my views were't really any different then than they are now. I don't want to get sidetracked with debates about "hard" versus "soft" atheism, so the bottom line is that I eventually realized that (1) atheism isn't about claiming to know everything; (2) you can admit that it's theoretically possible for some sort of god to exist and still be an atheist; and (3) being open-minded about the existence of god (as in, being willing to consider any new evidence, to the extent there really is any new evidence coming in) doesn't make you a non-atheist, it just makes you an open-minded atheist.
Anyway, take that for what it's worth. Your mileage may vary, of course.
But also, don't get too hung up on how people act here. First, there are a lot of atheists here, and like any group of people, there are jerks among atheists. Ergo, there are going to be some atheists jerks here.
Second, even those (which hopefully includes me) who aren't generally jerks can get a little testy, or just come across that way. This place is an oasis of atheist-friendly in a world that doesn't really like us. Everywhere else (and here too, sometimes), we read about how we don't have morals, are arrogant bastards trying to ruin their holidays, corrupt their children, etc. etc. So yes, sometimes many of us get a little bitter and angry and let that show when we shouldn't. And in general, this forum is a tough place -- but in a good way. You're not going to get away with logical fallacies or fuzzy definitions or inconsistent statements or factual assertions that you can't back up. People will call you on it, and sometimes not as gently as you might wish. Hopefully that doesn't turn you off this place, because it's worth it.
