Actually policing the movement and coming up with a coherent manifesto would be a good start. There's a lot more they'd have to do, but they've consistently refused to even consider trying it.
This is kind of what I mean. This seems like shifting goal posts to me. They had the whole harassment patrol thing on Twitter which I found sort of silly, personally, but I don't know how that would be described other than an effort of some sort. I certainly wouldn't call it an abject refusal to even try.
Like I said, I think it's a larger problem of shitty behavior on the internet in general, and I don't think anyone has a real solution at this point. I find it unfortunate that people use that behavior as an excuse to talk past each other.
