Chinese know that their media is pure propaganda.
Americans don't know their media is propaganda.
How can that be? you ask. The Chinese media is state controlled. The American media is free.
Sure.
Exactly because of that: the Chinese have long been aware that their media is government controlled. So they're suspicious of it.
The Americans are traditionally taught that their media is free. That it "speaks truth to power". That you can trust it. Used to be the case. But has not been for years now. The mainstream media is all of the Left. Some are literal voices for the government -- MSNBC, for example, often known as MSDNC for it echoes the Democratic National Committee daily talking points -- both by our observation and by caught-on-tape admissions by staff there.
Americans are becoming more aware of how biased their mainstream media is. But only slowly. We still know heaps of our friends and relatives on the Left who believe that they are getting the truth from their CNN, ABC, or BBC.
