Ok so I just double checked, turns out it wasn't this subreddit I had the good conversation in, it was instead /r/conservativesocialist. Easily confused with /r/conservativesocialism really.

I'm not really sure I trust /r/conservativesocialist either but I at least had a genuinely real marxist conversation with them. I suspect if they're serious they will pick up the stupidpol crowd and rehabilitate them into something genuinely useful instead of something reactionary, focus on topics like the family and simply remove idpol(including anti idpol) in order to create a genuinely unique space, but instead I suspect that it'll just be a Stupidpol2 and it's clear there's a lot of brainworms in there.
