The long history of the Republic. Our Institutions have failed us whether it's slavery or the Japanese internment, Jim Crow, women's rights, LGBTQ rights, the hysteria after 911. But in each case we eventually recognized our mistakes and made corrections.
You readily acknowledge "Our Institutions have failed us" multiple times, but you're arguing they can't fail us again because of "The long history" - I think you're arguing against yourself. And while this is digging further into the past, you left out The Trail of Tears from your list - an iconic example of the president ignoring the law because he can. That man is now on our $20 bill, so it seems he's been rewarded by history.
Saying injustices happen and are eventually rectified is one thing (which seems to be your argument), saying injustices can never happen again is something completely different.
What are the corrections made relating to the treatment of First Nation peoples?
The Japanese internment has already been trotted out as a precedent for creating a registry of American Muslims. That doesn't sound like recognizing our mistakes and making corrections to me.
I say this in all seriousness: why?
