― Kurt Vonnegut, Mother Night

Yeah, I mean I hope most of the people aren't serious. My worry is that you can't really get a subreddit that large of joking racists without it being explicit that it's a joke. The subreddit almost assuredly has actual racists hiding among the kids who just want it be part of a counterculture.

And if you kept posting it long enough, and participating in that community long enough, it's very likely there would stop being a meaningful difference between what you posted ironically and sincerely.
