You effectively can't, at least in a purely in an additive way. Unlike Stalin this site uses democratic centralism not to maintain some kind of power structure, but as a way to provide an objective safe space for various people. The cost of that safe space is the curtailing of discussion about the practical aspects and difficult edges of organizing, politics and theory.

Switching to a more subjective moderation to promote discussion would put people at risk of having to deal with the discussions whether in good faith or not regarding things that may feel unsavory and unsafe. Also let's be honest, there isn't that much basic discussion of theory that goes on here in comparison to the shit posting, so the change really wouldn't matter as much.

Unfortunately the left doesn't have the easy simple problem of "eternal September" to contend with, we have an "eternal September" that has to be intersectional. It's in general a problem of trust, and it's a hard one to solve for online communities.
