For me the easiest tell is the up front, unprompted, and unsolicited declaration of nonpoliticalness. When someone takes the time and expends the breath to announce how nonpolitical they are, what follows is almost always a rant about how everything/everyone else is too political these days, and that of course leads into something between status quo advocacy and outright reactionary/regressive sentiments for some fabled time before those wicked politics were visible to the nonpolitical ranter. 
People that are hostile to service workers. Some just want to take some ideological stand against tipping when the service worker doesn’t really have a choice and needs those tips to survive in the current unjust system in a way where ideological purity gestures toward that service worker just look like being a greedy and sanctimonious asshole. The worst of such people will actually declare, shamelessly, that they believe that service workers don’t deserve a living wage. The implications of that are 
worthy.
I may get shit for this, but I’ll say it anyway: this hair and beard combo, seen on living people. 
I have yet to meet anyone in person with that look that wasn’t a chud.
(If one of you is a comrade with that look, I am sorry in advance for the prejudice and if I ever meet you in person I will atone by buying you a drink or something.)
Which character was this? Worst thing I remember was that quest in Kingmaker with the edgy human pirate self-insert character.
I’m also relieved that Baldur’s Gate 3 dropped the alignment system for a CRPG. It’s always been so annoying to have the computer hard-track an “alignment meter,” and now I can relax and focus on what my character would want to do.
Crinukh (AKA Kreia with scales).
Fortunately, I barely remember that one. It at least didn’t have a quest that fucked the strategy layer of the game until you completed it.
