A lot of people have posted since this reply. Yes, I realize you do not like theism. I may have forgotten the specific term. I did know know you called yourself antitheist or that it was a common thing. The movements are cleansings such as the French Revolution, the Stalinists, the Moaists etc. Once in a while someone decides its time for a cleansing, and it may be a theist or a nontheist, so I do not mean to imply antitheism is genocidal. It seems that antitheist is a political, somewhat more assertive word than atheist. An atheist is not taking action or is not opposing theism, but an antitheist is. The word connotes it.
I understand. Its what it ironically sounds like, however. If there is no deity then how can you oppose one? If I jump and shake my fist at God and threaten God (which could happen), what am I? Am I not a true 'Antitheist' at that moment? I both believe in and oppose God then. That is what this term sounds like, even if that is not what it means. If on the other hand I do not believe in gods, then I can only shake my fist at followers or practices and beliefs. Couldn't a better, more precise term be found?
