If a 66 year old man tells you that contrary to everything he's written on the matter, he has recently learned that having sex with children is wrong, is that a moment where you wouldn't personally get too bent out of shape about it?
I mean, yes we all change our minds about things. But is there no nuance to it at all? Do you erase someone's entire past as soon as he says "I've changed my mind, child rape is wrong"?
