I think you're quoting the wrong person here, but if not, my argument is about government overreach, not race.
No i'm reading. You're saying there is some correlation.
When in reality we weren't very free until about 1965
A lot more than civil rights we got. We got right to privacy, true freedom of expression, many women's rights. We did away with eugenics and forced institutionalization (which much of Europe still practices by the way)
The peak of American freedom was post civil rights act. Really right up until reagan we kept getting more and more "liberal" in a social and economic sense.
The famous case, "can't shout fire in a burning room", that justice was calling distributing a peace pamphlet during ww1 was equivalent to shouting fire. We had no freedom of speech until the supreme court gave it to us..
We weren't very free before that.
