I tag people that don’t converse in good faith. So there’s people who attempt to misuse the Socratic method to derail any conversation. People who are just blatantly bigoted and aren’t open to other perspectives. A tag helps me from getting sucked in by an interesting question.
And there’s people who aren’t necessarily good faith/bad faith. Like people I suspect are just way over on the Spectrum to where they will take everything very literally and no philosophical or theoretical conversation will go anywhere with them. I don’t avoid conversation with these types of people, necessarily, but I might approach conversation differently.
