The slave was always morally free, but kept in chains by the power of people who wanted him to remain subjugated.
So too with the Supreme court. Their rulings may represent power, but they do not represent objective truth.
So the objective truth is that 3.9 million slaves were morally free but kept in chains by the power of people who wanted them to remain subjugated. Got it.
The courts rulings may not represent some ones definition of objective truth, but they are the law of the land.
If you disagree with the courts decisions, you are free to disobey them.
