As a Canadian, I actually don't see much difference.
A lot of Americans accept the book bans or INSTIGATE the book bans. They don't like diversity, they rail against DEI even when the policies in place are just to make sure that women and minorities get a fair shake. They LOOOOOVE bombing foreign countries, finding scapegoats, coming up with nonsense bathroom bans.
90% of what I see from American news--left OR right--is Americans kowtowing to authority while their quality of life goes down the toilet. They just try to decide which colour of authority they're going to submit to.
This tiktok ban was started under Trump 4 years ago, and weirdly, the Democrats pursued it for 4 years, and now Trump might stop it! When people complain both parties being the same, they're not that wrong. There are some outliers, but mostly it's the same love for the police state, for bombing Palestinians, for letting children get shot in school. Chinese people and Americans disagree on exactly what form of un-freedom they're willing to accept, but they're not that much different.
And in the case of China, there are plenty of more local politics that people ARE involved in, just like here in NA. Chinese people aren't voiceless, they just don't pretend that they actually have a say in Federal politics.
And, like, I'm not ignorant to how bad the Canadian system is about this stuff either. I vote in Federal elections and get no representation, and our electoral system guarantees that I basically never will.
