I have been here about as long, though it doesn't feel like two years. I've decided it's probably how some people interpret left of center views.
Kind of like how my parents seem to interpret feminist as misandrist hell bent of world domination and not people who think compensation should be equal.
Either that or people hearing such and such communist country was right about X and interpreting it as that country was right about everything.
It seems like some thought terminating bullshit to me, but like you, maybe I've just not happened across this terrible scourge on Lemmy.
Not for a few weeks, then it will have been there the whole time so nobody needs to do anything about it.
