They are not mindless robots. They are doing the best the can living in a totalitarian state operating the most sophisticated internal surveillance ever.
How can you claim they the CCP has support with a straight face? First, says who? CCP-controlled media? Second, would the average Chinese person answer honestly? Third, the Chinese have never experienced real democracy. Asking them if they support the CCP is meaningless. It’s like asking a third-gen Red Sox fan if they support the Rex Sox.
Why would a totalitarian state allow 150M+ of its citizens to travel abroad annually pre-covid to experience 'democracy/freedom' yet despite doing so they overwhelmingly returned to their supposedly oppressive country.
As for 'real democracy' no country has it least of all the US which more accurately an oligarchic plutocracy with power held by select few/wealthy(ie top 1%).
Ultimately, they are sufficiently confident in their indoctrination that they are unafraid that exposure to other ideologies will lead to a rejection of their own. Where they are not confident, they do limit travel. See their cancellation of passports for Hong Kongers.
I will not respond to your whataboutism argument as it is beside my point.
The govt is confident that most citizens will see the downsides of democracy and how it leads to much social divisiveness and govt dysfunction as evidenced by the US.
HKrs fomenting riots/violence and breaking the law have rightfully had their passports confiscated to face consequences of their actions.
