To me, this demonstrates importance of good faith arguments. It indicates that yes, some people should be effectively silenced for their beliefs.

I say “effectively” because he’s right that it IS a good safety net when things you say cannot hurt you. People correct toxic viewpoints like “Why are immigrants the cause of so much crime?” only by being allowed to ask the question and getting corrected.

The ideal case of fixing bad faith arguments would be: Someone engages in repeated zero-effort fake claims as you described at the end, and after the first round is corrected, everyone involved in that conversation declares “All right, this is a bad-faith argument; you’re not genuinely curious about the response, you’re just trying to force a reaction.” And then, ideally, finding ways to de-platform the individual. Again, “effectively” denying them speech by simply not assisting them with theirs. To me, that’s the role of what many call “Cancel Culture”, and I’d want it to be a stronger thing.

I will also say: You made a LOT of claims in your post that the above poster did not make. I was very much considering a downvote, although I agree with the dangers you’re talking about. Ironically you’re exemplifying some of the problems with cancel culture taking effect without conversation and understanding.
