As most internet arguments, the original examples were a bit flippant, pot and slavery at opposite extremes. Yes, the shifting balance between some natural order and polis/federalism. I am saying 'same argument' you are saying 'opposite arguments'. I am meaning the same thing. It is the balance line, I was saying 'same argument' as in arguing over the point where to draw the line, not two different argument pushing from both sides.
Yes, today, there is a 13 amendment. So technically slavery is settled?
But I have heard many people use the argument that the Civil War was about 'states rights' (not slavery) in the context of today. As in re-contextualizing, saying that generally the causes of the Civil War, being 'States Rights', was actually correct, and Lincoln went too far trying to keep the Union Together. That the states should be allowed to do what they want, which generally would re-instate slavery. If a state were to secede, then the constitution would not apply. And generally that is the argument, that the central government has over-reached, and we should split.
Of course, nobody is saying bring back slavery. What is being said is that we need to join the Church and State into one, form a theocracy, and women will really just be for babies. That is an actual position people are taking today, and they use the 'states-rights' as an argument.
