Astro was being obnoxious and disrespectful. This isn't direct personal interaction going on in good faith. It's an absurd public spectacle. It's an entirely different situation and one in which people's judgement changes drastically, losing perspective.

I guess maybe I did not read the entire comment string, since I didn't notice any 'obnoxious' comments from Astro, or much of an 'absurd public spectacle'. You may be right about that.

Dfranke basically isn't involved in this discussion. That's a good way to be. Some people have taken it as an excuse to push their spivak related political agenda but he has (wisely) chosen not to try to desperately justify himself.

Agreed!

Guilt would not be serving him in this instance and he has the opportunity to release that feeling and move the stimulus response pattern (disapproval -> shame -> supplication) one step closer to extinction.

I would still apologize. That is the person I've chosen to be (and by extension, the person I've chosen to represent myself as). It may not produce an overall 'good' outcome, but I'm not sure what you define as 'good'. I've never been treated with disrespect by people I've apologized too.
