I'm starting to suspect that the media, police, government in all its forms, just used to filter them all out. File their reports and letters in the wastebin.
I do wonder whether we've now just given those people an ability to talk to the whole world via Twitter/Facebook/etc., who aren't filtering them out.
So perhaps the narrative was always there, but pre-internet was easily filtered.
If you want a fine example of this, look at the push against modern medicine. Folks were eshewing "European-style medicine" for quite some time.
The US Took a really, really long time to eliminate lead from paint and gasoline, comparatively, even though we knew about the harm.
We knew things about climate change before WWII, and the denial then was pretty strong. People were scoffing about Earth Day when I was a child - I'm 42 now.
Anti-maskers were about in the 1910's with the Spanish flu. The anti-vax movement has been around since.. well, around the time we started to have vaccines. Yes, folks lined up for them, but not everyone.
It is a whole heck of a lot easier to be vocal about it now, though, and easier to reach others to try to convince them.
50 years ago the U.S. put a man on the moon, following the coattails of the civil rights movement, meanwhile suffering through one of the most corrupt presidencies, a resurgence of white supremacy that would echo for decades to come, and the beginning of an ignorant war that would destroy the lives of many tens of millions of Americans (the war on drugs).
And here we are, today, with an American company SpaceX yet again redefining humanity's reach and we are again suffering through easily the most corrupt presidency to date, white supremacy, and ignorance that is destroying American lives.
I think like many it's hard not to look at America today and worry that things are worse than they've ever been. But I think in many ways you're right; America has always been like this. A violent cocktail of the best and worst of humanity, shaken, not stirred.
Just because you watch TV and have a bad Facebook feed doesn't make it America
