You don’t want to have a bunch of anarchists in one city preaching about unjust hierarchy and a bunch of MLs in another city talking about a vanguard.

I mean if those are the conditions for those places how else are you supposed to do it? If theres a large presence of one group in one place and a large group in another that's just what will happen either way. But this isnt really how DSA works either way, specifically to avoid this very scenario of splintered off chapters. The chapters in order to become official have to undertake certain points of unity, no ones really going around using the chapter to preach their specific tendency or specific ideology. The work being done is less so ideological in that sense and more based on direct engagement with the local community based on issues that are actually important in those places. I agree it creates a sort of lack of ideological rigor since we don't push onto people the specifics of these ideas but rather use issues to gain mass support for a socialist movement. People can sort of go from there if they want to then join PSL or a caucus and concentrate on specific work. Its a general conduit for now seeing how underdeveloped the left really is in the US still.
