“Would this person’s attitude make them more unpleasant to work with than others I could be representing in my already limited time”, or something to that effect.

Someone who spends their free time hacking university printers to distribute white supremacist propaganda and is a proud member of the “Gay Nigger Association of America” trolling group would likely not pass.

"will this person be negatively perceived by a jury of their peers, or, especially, a jury of 3 federal judge? And, will this person say dumb shit that torpedos my case for reasons other than its merits"

"Is this person going to say idiotic nonsense that tanks the case because the judge or jury thinks they are just awful?"

Weev may have been a good test case if he wasn't a white supremacist.
