I feel like the kind of shit marginalized people go through in the imperial core tends to be inherently radicalizing in an anti-capitalist direction without necessarily being radicalizing in a pro-communist and anti-west direction.
That makes a lot of sense considering even the most marginalized people in the imperial core have the privilege of not having to worry about bombs being dropped on their homes, CIA backed coups deposing their democratically elected leaders, nor the general all encompassing horror of imperial resource extraction. The result is that western marginalized and privileged citizens alike will both readily accept the never ending deluge of atrocity propaganda against AES emanating out of essentially all western media outlets.
If you believed in literally everything the CIA said about AES, how would you feel about countries like the USSR or PRC? At that point, the red fascist rhetoric actually makes sense. How many fascists should you allow to sit at your table? 0. It's insidious, and it has broken the brains of too many otherwise decent people. For that reason I try not to judge people like your discord moderator (other than for unironically being a discord moderator) too harshly for things like this.
I don't think people within the imperial core in general will soften up on AES until real communist organizations can build up local mutual aid networks to support the most precarious of us in their communities. Ideally they'd provide necessary social services running parallel to the rotting remains of the social safety nets once maintained by western governments until the fall of the USSR. That would lend to us the necessary position of public trust to displace the misinformation put out by corporate media by providing relevant education on communism, specifically AES, where the public education system has purposefully failed. Deliberate agitation on this front is very necessary in that there is no horrible experience one can endure in the imperial core that would result in intuitively figuring out we need to organize society in a similar way to AES countries.
