Show me in the Constitution where it says education is strictly a function of local governments and any interference is a violation of "states rights. Take your time.
It doesn't, and I never said it did. But it does say this:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.
Is the power to control education delegated to the United States by the Constitution? No.
Is the power to control education prohibited to the states by the Constitution? No.
Does that mean that, according to the Tenth Amendment, the power to control education is reserved to the states? Yes.
I don't get it...you seem to be arguing both for and against local control.
