Overstating the case for Athiesm.

[Angrboda]

I'd say you're adding some variant of humanism, the belief that human life is central and important. The values of atheism do not commit one to action because it isn't a set of values. Atheism plus humanism does commit you to action because it does assert a set of values that, arguably, are threatened by theism. I agree with Simon, you're adding things to atheism that are neither essential to it, nor entailed by it. The question of exactly what you're adding may be an important distinction, but you've moved the discussion outside of the purview of atheism qua atheism by doing so.
