And Jack Churchill captured Nazi outposts with a longbow and a broadsword, but if allies armed every soldier with longbows and broadswords, something tells me that we'd be under Nazi occupation to this day.
Some great things are done by great people, but they don't necessarily scale well.
This misses the point (that the author of OPs post nailed). It doesn't matter that it doesn't scale. It works, and censorship doesn't.
Do you want a (difficult) method that works (personal involvement and direct conversation), or a simple, easy, lazy one (deplatforming/cancel/censorship) that doesn't?
200 people isn't very much. Twitter has 192 million users. Assuming (extremely generously given that twitter is on the Internet and has a userbase that skews younger) that twitter matches America's partisan divide, it probably has around 90 million users.
It seems unlikely that at least a thousand people out of 90 million aren't gullible enough to be swayed by hellbanning.
Hellbanning has a history of working well for deradicalization of online communities that were a lot worse than twitter is; Jeff Atwood has a good post giving a brief look at the history of it: https://blog.codinghorror.com/suspension-ban-or-hellban/
That's not proof that any one actual person was deradicalized, which was the metric.
Mr. Davis has 200 examples. I'm only asking for one. His method works. The deplatformers' citation of their own platforms only proves that they control their own platforms, not that any extremist view was changed.
THAT is how you beat fascism. Not censorship.
Lazy programmers trying censor via bits and bytes are never going to accomplish in a million years what Mr. Davis already has.
