The lack of slack for anyone who is in your way, not going fast enough, of other ethnicity, etc. is markedly more obvious than even a few years ago. If I were to go back further in time, the difference is even more pronounced. I remember when people largely obeyed traffic laws and wouldn't think of being uncivil in public (or private). They were also welcoming of persons of other faiths and colors.

Fox news viewers, Limbaugh/ Hannity/ Ingraham listeners will blame Obama and "democrat libruls", while others (like myself) will blame Trump for his rhetoric. So what do we do with that? The 24/7 bashing of anything "librul" on AM radio in the heartland, and Armed Services radio has taken a toll. It's largely all they get. Their side will argue the liberal media is equally biased, now even just "Fake News", and in defiance, go even to even more extreme (InfoWars, Brietbart, Q-Anon, etc.,) much of which is total misinformation and conspiracy-theories.

I am pretty well (and sadly) convinced that we are well into the divide that cannot be bridged. I just do not see how you fix this.
Optimism in rare supply. Sorry. Opinions welcomed.
