It is absurdism. It is dismissing the 10th amendment because the argument was also used for slavery. No one is thinking that states rights wasn't an argument used for slavery. But this is arguing vegetarianism is evil because hitler was.
I argue it isn’t absurdism when the evidence is clear that the idea of state rights is continuing to be used to subjugate in direct conflict with democracy, versus the actual collective and agreed upon belief of deferring to states rights and putting power closer to the governance of those states.
Historically, it was slavery. Now it’s immigration, reproductive rights, etc. History doesn’t repeat, but it rhymes. It’s always about control exceeding genuine governance. Maybe that'll change, but until evidence and outcomes demonstrate otherwise, "the purpose of the system is what it does."
