Again, for casual readers: Chinese people in the US who don't support squashing democracy fighters in HK (I think/hope that's the vast majority of them - maybe more hope now that I'm being downvoted) are awesome.
Surely, "I'm confident I'm not gullible" is the primary risk factor for actually being gullible.
At least, that's how I see it...
Fortunately, HN was also blocked where I worked at the time, so I already had a proxy set up. That worked fine. How subversive of me!
Which, we could say is because brainwashing since youth and perhaps there is some truth to that.
But I think likely the biggest thing is the same thing that motivates everyone else. Self interest. They want to see an expanded China with greater say in world events and greater share of the economic pie. Because it would benefit them. They see disruption or anything anti CCP as contrary to that goal.
