I post sincerely in Off Topic (cfb thread), FC, Election & History Games, and occasionally the gov & congressional boards (when there's discussion of Florida, Chicago, something I know about and can sincerely add to the conversation)
I post in bad faith/troll on 2020, USGD, and most of the time on Individual Politics
I rarely if ever post on IE/Int'l General but I read them quite closely, always a decent experience
My actual answer is somewhat close to this ... I never "troll" or whatever on Off Topic of Forum Community, and usually never in Individual Politics or the Demographics subforum. When I do post on the shlttier boards like the elections ones or USGD, it is either because I am extremely bored or believe I have found someone saying something disingenuous or something that reminds me of something else I am interested in and decided it's worth responding to, lol.
