Atheism & agnosticism are two very different things, BUT they are not mutually exclusive, do you understand what i mean by that?
They are mutually exclusive in the simple idea that you either claim to know there is no God, or, you claim to not know if there is a God.
"activist-evangalistic atheism" does indeed sound very ugly, but thankfully, it does not exist, so we can sleep safely in our beds tonight.
What? You simply cannot be saying that people like Madaline Murray O'Hair or the anti-pledge of allegiance atheist father in San Francisco are NOT being both activists and evangalists for their cause??? Atheism is as much a religious belief system to them as Jesus is to the Southern Baptists - and they are just as public and in your face about their belief as Billy Graham or the Witnesses ever were.
