While I agree that the term state's rights is largely a reference to slavery, I did use it here for brievety. There were and are definitetly arguments about the distribution of power between state and federal branches of government and responsibilities. Part of that balance was why the senate was created, and similar structures were adopted by many other democracies in the world and I do see the arguments why it serves a purposeful role. On the other hand the EL was never about that balance, it was always largely about the southern state wanting a disproportionate say without giving slaves the power to vote. I'm also not aware of any other country adopting a similar system (probably somebody will point out a counter example though).
