Free Speech Is a Principle

I hate that term free speech. I don't ever use it because it means so many different things to different people. Free speech is a principle. It's like an ethic. If Elon Musk says some opinions are not allowed, he does not believe in free speech. Let's talk about doxing. Do you consider republishing someone's contact information to be 'doxing' or something else? We got to respect people's privacy, but also at the same time we got torespect people's speech. Where do you draw the line?
