I am under no delusion that the USA is innocent, nor do I believe that it is necessarily a good force in the world.
However, The USA is powerful country. What do powerful countries do? They do things to further extend their power. Actually, that's what COUNTRIES do. That's what humans do. It's not about good vs evil, it's about economics. The USSR did the same thing when it was around, Both Russia and China do the same things today. It is no secret, and only someone brainwashed by their nation's media would say otherwise.
Next, Do you even have any idea what your talking about? The american credit score is nothing like the Chinese program. The American credit score is a system that is designed to represent how reliable someone is when it comes to paying debts and bills. In case you haven't noticed that's not what it is in China. China is attempting to implement a system that rewards "good citizens", and actively deters people from conversing with those with lower scores. In other words, This is social engineering, to an unprecedented extent, and It's stunning that your trying to justify or downplay it.
Now, put yourselves in the shoes of Hong Kong. They were unwillingly given over to a country nobody wanted to be apart of. A Country notorious for it's human rights violations, and total disrespect for the idea of freedoms, And you've watched that country continuously encroach on you're autonomy. They are scared, and angry. This is not a situation where peaceful protests will do anything. Fear gives way to anger, and anger gives way to violence (and suspicion) The things happening in Hong Kong aren't surprising, and they aren't unique.
Finally, What? Your going to point to the west's occasional problems with racism, (especially given that you've provided zero proof for this argument)? Even given all the things China has done to it's own people? And your point about "banning Muslim countries" is patently false - at the very least misleading. A couple of years back when Trump passed that law, it had absolutely nothing to do with race, or any prejudice against Muslims (if it were, he would have banned countries like Egypt, Saudi-Arabia, or Indonesia). It was a ban that specifically targeted countries with a history of Terrorism, and general instability. Again, total misrepresentation, and really shows how little of a clue you have.
