2. This link is about what's happening in Hong Kong, not the US, and this sort of what-about-ism isn't informative or helpful.
People are (rightfully) outraged when a protestor dies in Hong Kong, but protestors also die in the US.
For example, the Kent State shootings: https://en.m.wikipedia.org/wiki/Kent_State_shootings
The point is that if you’re demanding a certain standard from China or other countries, you should demand that in the US as well.
America not being a dictatorship, there are people demanding this. Through elected leaders. Through independent courts. Through Constitutionally-protected assembly and protest.
None of the above apply in China. And they’re rapidly eroding in Hong Kong, too.
Yes, we should be outraged by police violence in America. But it’s a matchstick to the blast furnace that is Xi’s regime of secret police, political repression and concentration camps.
