I say this as somebody from a /pol/ background myself. Because I've never bought into any of the cultural or super racist elements of fascist ideology that circulates on /pol/ but have always found myself critical of leftism too, resulting in me having no real "home" per say to discuss things without my opinions being unacceptable.
Point is that we are all ideologically and personally evolving from exposure to new ideas and ways of thinking and simultaneously unlearning ideas and theories we are no longer interested in or find relevant to our personal take on the world. Right wingers are just like left wingers and have arrived at their position for what they consider completely rational reasons because of what they've been exposure to up to this point, and gatekeeping due to the perceived ignorance and brainwashing of opponents prevents those few people that can doubt their dogmas from being accepted and learning about the other side of things and seeing that their enemies too arrived at their points for rational reasons and this can lend to a mutual understanding across both sides as people pursue what they believe is right together.
However I rarely see this kind of engagement on the chans or elsewhere due to specific ideological lines that do not tolerate each other enough to seriously engage with each other and hence create echochambers for radicals.
I figure a chan managed by /leftypol/ administrators that tolerates fascism specifically within the context of debate, refutation of propaganda, and reeducation would be pretty successful. I don't know, maybe something like rtspchan(reeducation through shitposting chan) with a specific board pipeline for people to go through. >Debate
Board for undoubting fascists to debate head to head with leftists.>Refutation
Board for doubting fascists and the refutation of propaganda.>Reeducation
Teaching and education pipeline to instill theory for those who've dropped their beliefs and are ready to accept leftism.
Maybe it can host some essential books as well, and the presence of a specific zone for spoonfeeding curious fascists would lead them away from pure leftist areas. Sorry for rambling it's just something I'd like to see and that I'd use as an educational resource if it existed.
