Plessy was wrong, but so was Brown, though for different reasons. Again, the Supreme court is often like a meat cleaver when it needs to operate more like a rapier. It went too far in Plessy, and it went too far in Brown. As a matter of fact, the hallmark of the Supreme court's landmark decisions is that they generally go too far.
Supreme Court decisions have everything to do with law.
In the manner that Actors represent Doctors on Television. As i've mentioned, often the Supreme Court decisions have little to do with law, and a lot to do with politics. Not even Liberal legal scholars try to defend Roe.
Different people can have very different opinions on legal issues.
But they can't all say they are correct. The one which is, must necessarily renders the rest incorrect.
“But they can’t all say they are correct. The one which is, must necessarily renders the rest incorrect.”
That’s why it takes at least five like minds to render an opinion that stands.
