Thinking a bit about the history of the US and how many times public & official opinion got it so wrong. Just a few examples.
Slavery - turns out that was wrong.
You had the southerners thinking they were right in the civil war. They were not.
Forcibly "resettling" native Americans. Who's the genius that thought that one up?
The Chinese exclusion act - not so good.
Interning Japanese Americans during WWII. Yeah, that was shitty.
Wrong on Vietnam.
Wrong on Ali’s conviction on refusal of the draft.
Still wrong on not giving black folks equal rights.
Wrong on the Iraq war.
Wrong on Trump and all his BS including the Muslim ban, the "wall", etc.
So there are large parts of the US society and the Govmnt that consistently get it wrong.
How come they’re so shitty at this “common sense” thing?
Yeah they get it right too at times but honestly some of the decisions are so clearly wrong how could they not know that at the time? Their knee jerk reactions are
