(Apologies if this is too much a personal anecdote for HN) Honestly, this is one of the indicators that forces my distrust of the modern family of social discourse. My own suspicions have a specific conversation in 2012 spooking a few hundred people (online), who lashed out with such odd phrasing that it spread contagiously to whoever they met... And formed the chimera movement we see now.

...I might outright have an alternate history of the entire '10s "Culture War". Or I might have gone paranoid. Of course I can't prove any of it. I'd love an answer to your first question myself.
