This is not meant to speculate on van Rossum’s health, just trying to point out that there are situations where apparent rudeness may be out of the person’s immediate control.
(Also, personally, if I were behaving poorly I would much prefer people to say "hm, 'geofft is being rude but I know he's a better person than that and can improve" and not "hm, 'geofft is being rude, that's just the way he is, I wonder if he's got mental health problems.")
Basically agreed.

That's a lovely thought, but no. When I've had bad times, my social skills and emotional cope would sometimes go to shit and leave my technical skills intact.
People are screwed up. You are, too. I hope your business partners and allies don't hold you to the standard you're bearing when your time to behave badly comes.
