And with countries like China or India having a larger market, what does America want to do? Not let them invest in the US, accepting that different viewpoints will be expressed? Declare them invalid?
One of the positions that Americans broadly have always held is that when ideas are exchanged, the people overall can figure out what the good ideas are and what the bad ideas are, that's in fact the basic assumption behind liberal democracy. So if these Chinese cultural exports are just propaganda and all around awful, surely Americans will figure it out.
If there's something to them, and they're genuinely valuable and give a different perspective, then it would be bad to try to suppress them.
So by liberal democracies own standards, I find myself puzzled by the flat-out fear of foreign cultural imports.
