If he considered himself a counter-example to your claims, he probably would have said so upfront.

Do you support Elon's censorship of antifa accounts?

Difference between me stopping you from wearing shoes in my house, and me stopping you from wearing shoes in yours.

Not really, no. All three cases (US Gov, Turkish Gov, Elon) are censorship of the public square in the end. I'm against all of them. As far as I'm concerned the US constitutional standard for free speech should apply to any platform above a certain size in terms of daily active users that facilitates communication between those users.

So to you, there’s no difference in preventing me from wearing shoes in your house and making it illegal for anyone to wear shoes in their houses?

This is tautological. Death threats are illegal speech because we decided to make it illegal speech. Something we could do for other types of speech.
