And if you say things that the law says you can't say on social media, you should be stopped.

Note I said "the law", which is created by the democratic process (in theory anyway. Stop laughing at the back.) This is as opposed to the whims of a private company.

As for what things the law should forbid you from saying, that's another matter, and orthogonal to this one.

Your speech, whatever it is, is protected in public places.
