..."because it's an accusation, rather than, as it were a conviction"

Let me say something about the first point, the label... the label one has. Yeah, to be called an atheist it's a negative view, and it suggests that one is a sort of professional atheist... you spend your life arguing against God, the way Russell did. And I think that's a rather undignified and pointless procedure. Once you've decided there isn't a god, there's not much point in inveighing against it, unless you think that huge harm is done by the belief in God. But you don't... nobody spends their time trying to prove to others that the Greek gods don't exist. You know, you just decide that they don't, and that's the end of the story for you.
So I like to distinguish atheism from antitheism. Antitheism is opposition to theism.
