I mean, I was intending "accept" to be an actively, but not necessarily strongly, positive stance. If someone finds a situation "acceptable," they're usually assenting, not just "putting up with" that situation.
Is Accepting one's fate a sign one is happy with it at all, or just that they aren't fighting it anymore?
Is Accepting the complement of Rejecting? Rejecting seems negative, and the opposite of negative would be either positive or neutral?
Should the neutral category be "Fail to reject"?
