Well, I believe in all kind of things: honesty, friendship, human rights, scientific evidence, gender equality etc. I don't believe in fantasies. So if you talk about god(s), I'm a critic. First: Where is the proof for a god? I mean EVIDENCE. The Universe is NOT the evidence! Of course one could say that being a critic is some sort of dis-belief. But my criticism is usually against absurdities and the oppressive natur of organized religion.
Atheism is NOT a belief. It's a lack of belief in god(s). It's that simple. But theists tend to throw all kind of stuff into the concept like satanism, immorality, or any kind of other beliefs. And that's just another fantasy based on bias.
BTW, here's an interesting page for you to explore:

What god(s) are you a theist in or an atheist towards?
