While I agree these are all concerns, I am skeptical that this is a modern phenomenon. Were people a generation or two ago really less emotional, or less prone to black-and-white thinking?
I think they were probably the same they just didn't spend as much time thinking (for lack of a better word) about this stuff. It wasn't that long ago that there was only 15 minutes of news a day on the TV. People were thinking about it less because they didn't have the option to plug into political hacks spewing nonsense literally 24/7.
