Of course, the irony of a extreme politics being combated by a group called Sigmarxism is entirely lost on Vice.
There's something I've noticed when dealing with lefties in the culture war, ever since the start of GamerGate, when I was in the far lefty bubble but got expelled for questioning the narrative.
Basically, lefties -- especially extreme lefties -- don't believe something like "Sigmarxism" is political. They certainly don't see it as extreme political. Lefties don't see their own politics as political viewpoints. To them, it's "being a good person" or some smug as fuck variant therein.
Basically, it's religious views. They worship their own moral superiority. It's why they have no qualms in trying to destroy people that disagree with them, it's why they have no qualms about lying through their teeth if it serves their interests, it's why they have no qualms about trying to "fix" every hobby and fandom they enter.
They literally cannot comprehend that someone of good moral character would ever disagree with them, and they certainly can't comprehend the mental reasoning behind people who do. No, literally -- Righties understand Leftists (but disagree with them), but Lefties have
no fucking idea how righties think. It's a complete and utter lack of empathy on a scale I don't think many appreciate. (Edit: And here's the scary thing -- that same utter lack of empathy? It's a primary symptom of Sociopaths.)
It's why you can have a forum that has explicit rules against political crap and still have to deal with leftyfags bringing it up all the goddamned time. Because to them, Marxism and Leftist Politics and constant activism and the like isn't political, it's "common sense" and "being a good person." But if you tell them to shove it,
that is suddenly political. And if, god forbid, you support a center, center-right, right, or even far right stance, that's not merely political, it's not merely hate speech, it's
heresy against leftism.
Bringing it back to Warhammer 40k, these types literally cannot understand why someone would ever joke around as an Inquisitor ranting about Heresy. They cannot understand why anyone wouldn't be outrageously offended at the idea of "Fascism" being the "Good Guys." And the concept of people opposing their efforts to "fix" the setting is completely incomprehensible to them, to the extent that they have to make up some cartoon NaziFascist in their mind to explain it.
