That's the situation we're in. The damage that was done with these court decisions against traditional marriage has to be undone. Then, let the states decide, but with no interference from the feds.
Saying "it's an issue for the states to decide" at this point without some corrective action is meaningless.
Making it clear that this is a state issue, and not a Federal one is the first step toward the corrective action we all want. The Federal Courts have to be constrained, and it is within the power of the Congress to do this through legislation.
