> They (or at least, they used to) insure that "state's rights" advocates don't implement curricula that teach children that the world is 6,000 years old and flat. They are in the process of being dismantled.

That is, in my view, a good thing. We should not be a monolithic nation and were never meant to be. If the people of (insert state here) wish to teach their children things I don't agree with, or even things which are outright false, that is their right. Nor does it hurt me in any way.

One of the great problems with our country today is people trying to get the federal government to control more and more things. That is directly responsible for much of the division in our country, as federal elections (especially for president) turn into this big fight over who is going to get to impose their dramatically differing way of life on others for the next 4ish years. To reduce tensions, we need to return to the original design: decisions about government should be made as locally as possible, so that the government can reflect the very diverse needs and cultures that exist across our country.
