Is it not obvious? Replace “fairly despicable” with “white nationalist” instead of whatever anyone might imagine could make a mathematician despicable?
Why does this shorthand upset you?
A shorthand is generally unambiguous in context; this was not.
Why does it matter to you so much that OC is unambiguous?
Because I'm not on-board with every moral failing that is called “despicable” by someone being disqualifying or even relevant.
I am not upset. It is obviously obstusely, impenetrably vague. What is your problem?
