The 1950s were not nightmarish for anybody actually living in them. Racial minorities, though still mistreated, were mistreated a heck of a lot less than in decades prior and had much more economic opportunity though they were starting from lower on the ladder on average than white people.
That economic opportunity is what everyone wants back.
The fact that you can consider the 1950s in the US a "nightmarish historical moment" is nonsensical, to put it very, very charitably.
Well, you can go upthread and read about the lynching of Emmet Till, or familiarize yourself with any of the many ways in which the Jim Crow laws were formally and informally enforced. You can look at the photograph of Emmet Till, even, before or after he was lynched.
Maybe you have thicker skin than I, but I think living in a community where you could be brutally killed for any or no reason, and knowing that your killers would not be convicted, is a nightmare.
Funny you mention that. I was this >< close to preempting your comment by mentioning him but figured I'd give you the benefit of the doubt.
Ask yourself, why do you even know Till's name? Why did Till's killing spark national outrage when 20yr later that would have gotten barely a peep out of people? Because times changed and that kind of behavior was no longer excusable.
>but I think living in a community where you could be brutally killed for any or no reason...
Till was killed for violating social norms (that he presumably was not sufficiently aware of). His death was no different than that of a peasant 1000yr earlier killed for bad mouthing a local lord. It's tragic. But it wasn't without reason, though we may think the reason flimsy and disagreeable.
And this time I am going to head off the inevitable reply by pointing out that I am not defending or justifying Till's killers, just explaining the context.
Those who fail to understand history...
People still felt the need to propose an anti-lynching law in 2020 [0] so maybe lynchings are an ongoing problem. There isn't anything to argue about without actual evidence.

Given the frequency of folks literally marching around with Confederate and Nazi flags, you've overstated your case here. Perhaps that's what you want, but there's a significant movement in support of a white ethnostate. That movement has representation in the Republican party, and for example Tucker Carlson is wont to voice its talking points and his show is one of the most watched on cable TV.
Pretending that racism was just a blip in the past and not a present and ongoing problem, or ignoring it because it didn't impact your parents, is at best naive. The Emmet Till case was a stark reminder to Black Americans that their lives were worthless in the eyes of the law and the white citizens who had the power to change it. To call that event terrorizing is not remotely a stretch.
