There are way too many of those people out there, they are organized, and they have been emboldened by Trump, Hawley, Cruz, and the entire right-wing infotainment complex. They are no longer afraid to show their faces. They are no longer afraid to say the quiet parts out loud.
The exposure and emboldenment is really all that's new. There have always been way too many of "that sort" of people out there, which is either a cause or a symptom or both for never having really healed after the Civil War. And they've always been organized, since the Civil War and onward. They just went underground starting in the late 1800s and have stayed there under various names. The Trump administration and all the enablers you name, and more, let them back up to the surface and whipped them up by calling them "patriots" and "fine people."
These idiots (I mean people like Sen. Cruz, Pres. Trump, and others) have no idea how [expletive]
dangerous those people are, and always have been. Prior to the Trump Administration, the only thing protecting us from them was the general belief in the United States that extremism and racial supremacy were Bad Things. Sure, you could be your racist angry self among the Good Ol' Boys in your town. But you just "knew" you couldn't do that if you were going to head over to Disney World or elsewhere out in public. Now -- thanks to these feckless idiots -- you can drive your Confederate-flagged truck down the freeway, waving guns out the window, and terrorizing your political opponents with impunity. That's what these people have always longed to do. This isn't new. It's just been Generally Frowned Upon until now.
Oh, sure, they wrap themselves in the flag. But then without hesitation they beat innocent people to death with them. They ally with law enforcement, but then quickly show how little "blue lives" matter to them. It's never about the prosaically noble causes they espouse. They're angry, racist thugs. That's all they've ever been, and that's all they will ever be, no matter what empty, patriotic-sounding platitudes they sloganize. But because certain politicians are just profoundly ignorant of anything except the privileged environments they've grown up in, they think it's all just a game. They think they can dog-whistle these groups by stumping their cover stories and praising their efforts, and that no harm will come from it.
American politics has devolved to the point where the people who practice it literally think there are no actual consequences. The economy will somehow always be strong. Poor people will somehow always be docile and subservient. People with the wrong color skin will somehow always stay where they're put. America will somehow always be great. Violent racists will somehow always stay safely just under the surface. They'll always be re-elected so long as they promise to "own the libs." And, laughing all the way to their capitols, they'll always be free to exploit whatever presents itself, with no accountability. I believe it starts with holding politicians accountable. Who's going to do that? Other politicians? Voters who look at these decisions as no more consequential that a sports tournament?
