Deplatforming can't work- otherwise the world would now be as white-bread homophobic and misogynistic as it was in the 50's when blacks, gays, and women were deplatformed.
That kind of implies those social groups all had full participation on the social platform and were then kicked off it, no? I don't think you've thought this analogy through fully.
Please tell me you recognize the irony of your comment.
Your last sentence is essentially indistinguishable from the position held 50 years ago by people who also felt they were "morally right" in deplatforming.
