The Americans I’ve met in real-life were quite chill, and reasonable. But on the Internet I too have a feeling that they are expressing stressfulness more. It seems to me they can freely talk about the things they hate, and they do it, to the point many things on the Internet about the US are those. And it’s hard to touch grasses in Winter.
I treat these people like those who think the Earth is flat. Ordinary foreigners may not be actively followed by someone nowadays. But things like heavy censorship, starvation in certain recent situations, travelling restrictions, they may never experience them in their own country their whole life. Nor did their parents experienced something far, far worse. Those who live to tell the story maybe lucky or unlucky. They never have to tell those things only privately.
