Possibly because you missed the sarcasm/joke nature of my comment and gave a serious reply. I wasn't defining atheism as faith in no-God.

I was digging at the idea that someone would accept a claim on Faith, then demand evidence before giving up the idea, and how that is inconsistent. If someone can faith into an idea without evidence it should be equally easy to faith out of it with no evidence.

That it's not easy, is interesting.

Nothing -> belief in God, costs little and gains much.

Belief in God -> no belief, costs much and gains little.

Where by costs and gains, I include social acceptance, eternal life, favourable relations with a powerful being, forgiveness of sins, approved life habits, connections to history and social groups, etc.

It's not a Boolean. Or at least, from inside a mind it doesn't feel like a Boolean.
