It's low quality bait, but it's bait for sure, and you fell for it.
Mocking someone's illiteracy regarding history and political theory is not "falling for bait."
The OP is very vague. It basically says "some people pretend to be Marxists, but they are actually right wing," with no details. It doesn't say "hey, you know that weirdo who calls everything neoliberal, gets unreasonably angry, and makes everything about their obsessions is actually a right winger."
What exactly are you talking about? Are you describing yourself here? Are you the weird subliterate Biden Bro back again who pretends "neoliberal" is a made-up word that doesn't mean anything, because you've never heard the word used on cable television?
Flaunt that illiteracy, bro -- neoliberal has FIVE SYLLABLES, which explains why you don't understand what it means, lol. It's a word that has no meaning, which you can just keep repeating as a joke, because I guess that's what "humor" is like for semi-literate DNC Bros.
And this is why sociologists are the laughingstock of western academia. They don't even understand basic terminology that is commonly used by academics in other discipline if it goes above their cable news understanding of the world.
But that's clearly the user who got the most big mad about it. Why? They weren't called. Yet they clearly felt like they were. Based on what? The description.
You got owned.
You're literally arguing here that anyone who mocks someone's insanely inaccurate historical illiteracy (claiming that "right-wing fascists call themselves Marxists") is "big mad" at the person they're laughing at.
Admit that you got badly owned, dude. And maybe take some remedial reading courses so that your next attempt at "owning" someone else on the internet doesn't humiliate you so badly.
