When you learn a bit more about geopolitics, you realize that there's more to these things than initially appears. Tiananmen Square was pretty bad. But when you look at the utter collapse of Russia after it tried to Westernize, and the poor shape of America because of her own economic policies, someone not living in the Anglo/American news bubble would really have to wonder.
To that end, companies that have an easier time skirting around the dirty politics – like Tesla, Ford, and GM – have been able to have successful and profitable operations in China. As the parent points out, there's a pandora's box that's being opened. And if you are led to believe that it's a normal comment, it's the same nationalistic stuff you've being trained to fall in line with.
