Hong Kongers would very much like to choose their own leadership. I understand that you're arguing from a mainland Chinese perspective, but in so doing you're ignoring the people who ought to have the most to say.
I used to have your viewpoint, but after reading Lee Kuan Yew, and after several hours of cross referencing various interviews with the pro-rioters/hk democracy, and pro-engagement/neutral hongkongers, I conclude that most of the pro-rioters like Joshua Wong/Jimmy Lai at large fail to articulate anything of value other than "I want to turn the system upside-down" , while pro-engagement/neutral people know they want upward social mobility and more government involvement in fixing the housing and employment crisis.
Good for you. But I didn't refer to any specific pro-democracy figure. I am advocating for free and open elections where everyone, pro-mainland or localist, can choose the direction of the city.
America doesn't speak for Hong Kong and many people don't want America sticking its nose deep into their business especially through someone breaking the law by acting as a pseudo-foreign agent.
The irony is that Trump getting involved in pressuring for the release of Jimmy Lai just makes him look even more like an American asset.
