You hadn't refuted this point:

Physical Removal is a concept which was coined by Libertarian / Anarcho-capitalist Hans-Hermann Hoppe in which certain people would need to be expelled to have a Libertarian society. I don't agree with many of Hoppe's claims, but I think do that open discussion should be allowed to root out bad ideas or philosophies.

I'll add I suppose allowing for a "club ground" differs significantly from allowing for open discussion.

When an ethic generates information entropy, the ethic tends to root in the mind regardless of how immoral, unjust, or incorrect. That depends more on the worthiness of the individuals to integrate with each other, than any specific title or topic. Whether they advocate violence or not: if doing so without comedy infavor, then comedy out-of-favor would justify their ethic.

Creating an independent thread for each banned sub or account to deliberate on their ideology within enforcing (what I'd call) a hypofae frequent mode allowing only one comment per a preset period. A long wait requires more information entropy from external sources to maintain ideological stance paired with attachment to a critical thread.
