Ableist definition

I saw a user named Banno state that a thread was "ablest" and it was deleted. Could you please provide a defition of how ablest is defined?

From what I recall, in the thread user was talking about a theological argument which compared "sin" or "evi" to a disease in a metaphor. (He was not saying that "people who have diseases are evil", or something like that).

I just wanted some feedback on this, since I didn't see any other users in the thread who agreed with Banno's statement before it was deleted, thanks very much.
