I'd split #3 There are those who believe God certainly cannot exist, but also don't see it as any reason to be a smug asshole to those who disagree. Then there are those who think it's okay to be assholes, and they can believe that god cannot exist, or they can be one of your "agnostic" categories. I'd say 4 categories: - those who do not feel belief in god is justified, at least for now, but are not assholes. - those of the above, but who are assholes. - those who believe god's existence cannot be justified, but are not assholes. - those who are the above, but are assholes. and typically the assholes aren't too bad, because they believe they are helping others by being assholes, kind of like asshole "god warrior" Christians who think imposing THEIR beliefs and just being dicks to those who aren't believers are helping, in the end it's the same kind of personality behind both of them. I was around in the Bush years, i know what it was like to have the Christian equivalent of the atheist asshole around, and it was exactly the same kind of experience.
