No, I didn’t miss your point about athletes etc. But you said self-flagellation in moderation is OK. I don’t agree. I’d be crazy to say all kinds non-self-inflicted pain are bad. You made a distinction and then didn’t follow your own distinction. Here’s what I think, FWIW: pain in a good cause is OK; pain for the sake of repentance is wacko, even in moderation.
So you are claiming that athletic training pain is non-self-inflicted?
