Contrapoints, Gigi, Maya Henry were the first three that came to mind and from what I've seen all have wildly successful online followings, and a literal army of Twitter and Discord users to come to their defense. KF is the only site I'm aware of that bullies trans people, but I can think of loads of popular accounts and forums that happily go after Republicans, depressed single men, Christians, and any other group which the online majority has decided is deserving of abuse. I think the take "trans people have a hard time being accepted online" is pretty outdated now.
Seems to me that Transwomen just took the only scrutiny contrary to their own agenda temporarily off the net, putting one of the most technically competent hosting providers on the list of people who won't associate with them (people acting in opposition to Transwomen).
No comment on the hating on black people, as I learned long ago, platforms are not users of platforms, and horrible people can be found everywhere.
Despite all of this horribleness that apparently goes on with KiwiFarms, it still seems Transwomen is able to go on doing whatever it is it does.
Strictly speaking, your yardstick for empowerment measurement has a rather funny operating principle, as intuitively speaking, I'd expect the opposite result.
My comment about transwomen being disempowered is in the broader social sphere, where trans people in general are under social and legislative threat against their access to basic decency, public visibility, and medical care.
