I genuinely don't know. I've thought about that for a while.

Blue-team liberals are one thing, they can be varied in the brainworms that inhabit their skull so there is different ways with dealing/weeding them out. The process of "weeding" is important here because in the experience I had with my lib friends being around comrade peers and having different people engage against chauvinist ideologues when they pop up helps with "conversion". Lots of sources that they've never seen, evidence, etc. "Facts and logics" type of shit.

Red-team liberals I've had legitimate the best experience by just talking to them. Either they're vehement racist, transphobic garbage bigots or they're just misguided and it just takes a bit of encouragement in the right direction when they're already mad at the conditions that they exist in. Plus, you can lean into their biases and "switch them around" and eliminate them entirely with more social rapport.

Just by being close with people and actually giving a damn you seriously impact the way people think.

Leftcoms? They're dedicated true-believers in ahistorical bullshit and constant bleeding-heart tropes against authority. I genuinely don't know how to deal with them. Best way I can sum it up is outright "rejection". They just reject everything. They reject sources, they reject your ideologues entirely in some smug Stirner-style shit and have no interest in actually listening out to people. I've never managed to actually impact one.

Let them die nameless frankly. They can either get right or get left behind; if they don't learn after the next oncoming Night of Long Knives, they never will
