To be perfectly honest I don't think anybody has the answers to these questions. Some of the content creators I watch will directly debate Nazis/alt-righters and I feel like there are pretty clear benefits to understanding how they think and how they operate. Sometimes taking down the views directly causes people to leave the movement.
I guess its more so that I think that kicking Donald Trump off Twitter was almost certainly a good thing, as was getting rid of Parler. These are complicated questions, but I'm hoping to some extent the left can start having more conversations about our own ideas rather than being defined by our reaction to goofy radical right wing ones.
