I never claimed otherwise.And States DO HAVE RIGHTS. The U.S. Constitution limits those Rights, but it does NOT eliminate ALL states' RIGHTS.
My point was that the idea of "States Rights" has been used by people and courts to disregard many parts of the Constitution over our Nations history.
The civil rights movement of the 60's is a good example. Those opposed to inter-racial marriage used it to justify banning inter-racial marriages.
I believe you yourself have said DOMA violates "States Rights" since it doesn't give equal protection to all States marriages.
If I'm mistaken about that I apologize.
