I resisted becoming a Bright. I wasn't sure why for the longest time. Then I figured it out.
I liked the implicit rebelliousness and the bad boy vibe. "I'm godless! Who is more godless than I that I might learn from them!" [Nietzsche's Zarathustra].
But on calm reflection, I agree with pretty much everything the Brights stand for.
Being a Bright does solve one problem: I disliked how atheism pretty much means not-god-believing. It's a negative. Consequently asserting oneself as an atheist carries religion along with it.
