I think jingoistic China bashing pays better than putting the spotlight on America's various problems and shortcomings.
They did it in the 1970s and aside from brilliant Hollywood movies it wasn't a good decade for America.
The less introspection the better as far as the media and political interests are concerned.
How is it jingoistic when China is flying warplanes over Taiwan and their media is now making claims the US has flown 10 balloons over their territory and supposedly were about to shoot down one of them and feign ignorance about the ones they sent over to us? Or are you saying both sides are being jingoistic?
