Politics shoudn't be disturbering anger

Where's a book from the 00’s, it could be The world is flat : a brief history of the 21 century, there it's said that while Asia is dominated by the feeling of hope, the West is dominated by the feeling of fear. That was the 00s, is the feeling of the West now anger?

Personal examples. My older brother-in-law is angry at the response to covid-19, my younger brother in law is angry at our migration and integration policy. (To change Swedish migration policy seems to be as hard as to change American gun policy.) Both are angry in a way I find disturbing, and I know I can be in the same way myself, I too can get disturberning angry at politics.

If I should take an international example of anger in politics it’s easy to assume I only need to write one word: “USA”?

Perhaps we can just blame web 2.0 and associated black and white worldview, polarization, and ugly rhetorical tricks.
