Is it normal don’t value free expression?
What we see the more open people are about themselves is that most people aren’t very interesting. Just anecdotally on this site for example, a new person might expect to find a bunch of crazy weirdos, when it’s actually people who think that using drugs or being mildly promiscuous sometimes are substitutes for a personality. From a data perspective there’s a lot of evidence that people are mostly the same and predictable, and that almost nobody has very original opinions, skills, or abilities. By giving someone a couple short personality tests you can accurately predict major life outcomes, beliefs, mental health risks, job performance, etc. Most people are also mediocre even in their own career field, and the great artists like Ye or da Vinci, great athletes like Michael Jordan, or great statesmen like Putin are a tiny outlier minority of people.
Maybe instead of every mediocre person online having an equal platform to say they like watching the office or that those darn vegans are so annoying, an authoritarian regime should give more resources and a platform to the exceptional people to shine among the others. Also to be clear, I’m not claiming to be an interesting person myself, just that I can clearly tell who is and isn’t.
