I support completely free speech.
That doesn't mean I'm going to agree with-- or like-- everything people have to say.
If you own or control a platform and you ban people, rather than just having problems with certain specific things they've written or said, I'm not going to trust you.
I've lost trust in all the major "social media" platforms and all the data gatekeepers due to their bans, even when they've banned someone I despise.
I support free speech for statists, Nazis, ISIS, racists, everyone. Let them speak... and then use their words against them. Their words are the best argument against their beliefs. Shutting them up helps them hide. It lets them look like victims. Let them speak.
If someone makes a credible threat, then warn the target of the threat, but don't prevent anyone from speaking. Doing so makes you look weak and dishonest.
