Hmm... Let me try and state my concerns in a less-inflammatory manner.
First, I apologize for the curt parent comment. I slipped from the argument dangerously close to an attack against you, as a person. That is not okay in any circumstance, and I am sorry I stooped so low.
I suppose I should explain my point of view here. I am not a fan of the United States' foreign policy history, especially state-sponsored coups. I just found your statement:
> China never send army or CIA to overthrow other countries.
Incorrect given the information I have access to. All world powers, including China, have and continue to practice "soft colonialism", or Neocolonialism. The infrastructure projects in Africa were meant to serve as a common example of this occurring. Here's a more concise example from the EN wikipedia:
https://en.wikipedia.org/wiki/Neocolonialism#China
Note that this does not clear the U.S. or western powers of wrongdoing. In the last line of the above link, it points this out quite explicitly.
This makes more sense, then, when we look at the context of this comment, which is the growing concern in the light of the Hong Kong protests across the world with how the Chinese Government (not people) is seeking to change outside cultures to be more palatable to their official ideals.
