You're the one who brought up Independence Day. And again, your knowledge of history is shallow. I am able to remember when the schools became integrated [0]. I also know why the bathrooms at the rest stops in the South have two entrances ("separate but equal"). And I had a teacher who as a young girl was chased by the Klan.

What we have now is so much improved over what it was like just 40 or 50 years ago that anyone younger just can't appreciate the difference. I advise you to turn off your internet for a few days, go drink a beer & chat with your neighbors and maybe shoot some fireworks off. The internet amplifies biases - don't let it.
