PCM is shit because it reduces ideologies that killed tens of millions in brutal ways to funny memes. Right-wing authoritarianism isn't cute shit like the nords from Skyrim. It's gas chambers and mass graves. It's parents forced at gunpoint to dig graves for their families. It's blood, and horror, and death. These are serious topics and should be treated as such.
PCM is also shit because it gives extremists a place to go mask on and spam recruitment lines (tradwife! My ancestors! Social decay!)
Also, the political compass is basically astrology-tier political science, and I'm sick of people acting like it's the be-all and end-all of polisci.
