Curious to get some opinions: what, if anything, should non-members be doing about all of this?

I think it's reasonable to discuss informally in our own orgs & communities, to hopefully learn some lessons from it. Would the same apply to more open discussions (posting, articles, letters, or whatever) assuming it's done in a productive way? Is it best to let former/current PSL folks figure it out without added noise/pressure? Or is maintaining some amount of pressure useful?

What about for non-members working in coalitions and whatnot? Wait and see how things develop? At what point do they go on the "avoid as much as possible" list? I don't think they've reached that point yet, but that's the direction currently. Are we obliged to let them know publicly before things reach that point?

Edit: It really seems like their leadership is in serious denial. There are certain other orgs, who every new leftist is warned about by other organizers of other tendencies. It becomes the thing everyone knows about, the org everyone is warned about. And those orgs stop growing, turn inward, and become cult-like. It's how a lot of orgs end. And their leadership thinks they're preventing it, by repeating the exact steps that cause it.
