As a 100% atheist, I disagree strongly with every single one of your statements.

To elaborate,

> Most anthiests seem to be nihilists

Not true

> they're already (claiming to be) doing that

No, they're not

> the logical conundrum of "I don't need a God or theology to live a good life"

There's no conundrum or contradiction here, plenty of us live good lives

> our constructed definition of "good" comes from religion

Sounds like a made-up fact. I don't need an omnipotent third party to validate that taking another person's life, or stealing from them, etc. is not right. Empathy and the idea of "do unto others" are quite easily understandable and relatable outside of the context of religion.
