@JetlagJen @skye I... sort of half disagree on the "impossible to quantify" part? Like, it is correct in the most literal sense, but IMO the more important thing is that it's not really *necessary* to quantify exactly.
Generally speaking the people who are unwilling to change, are *very very obviously* unwilling to change, to the point that to anyone vaguely familiar with the signs, there's really not any doubt.
That leaves a small amount of cases where it really is difficult to deal with as a community (think "always immediately promises to change but never does"), but those are generally few enough that they can be collectively handled on a case-by-case basis.
@joepie91 @skye yes.
This is additional detail and nuance that I hadn't fully thought through, but I think it's accurate. Thank you for adding it.
