Sensible? Reasonable?
I could never pin down any self-avowed athiest on what he did and didn't believe. Nor was I impressed by that "there is no god, god is impossible" <---> "just a lack of belief, you can't prove a negative" motte and baily game. That may be one way to win an internet debate, but not genuinely open minds.
This is before the fact that these types obviously hate something they claim to disbelieve in. Militant Athiesm was just a front for high-modernism, statism, and hedonism.
