In US, the government may not come for you like China.
But in US, there are multi-national corporations, NGOs, think tanks, activist groups, social media mob who can just as effectively and "humanely" strip your power, influence and livelihood just as well as Chinese government can.
Also at least with China, rules are pretty black and white. Don't mess with the Chinese government's received view. However in US, it's ever-changing goal post, where opinions, jokes, scientific studies which were mainstream just a couple of years ago can potentially get you fired, bank account closed, socially shunned and be labeled with all kinds of things.
Is US actually better about freedom of speech than China in practice culturally?
