You've just gained an immense amount of my respect, which an upvote alone could not properly convey.

Gwern would have gained more respect from me if he withdrew with tact rather than making an exit in a way that also scores a point and reinforces the frame that Alicorn is behaving irrationally*. This doesn't mean I am saying gwern's approach was somehow inappropriate (I'm actively saying nothing either way). Instead I'm saying that being able to withdraw without losing face or causing the other to lose face demonstrates strong social competence as well as the willingness to cooperate with others. Exiting with a pointed tap-out does demonstrate wisdom and a certain amount of restraint but it is still crude and neutral at best when it comes to respect for the other and their emotions.

* Standard caveat for all my comments: Unless explicitly stated I am not making any claim about sincerity or intent when I talk about what effect or social role a given action has.
