> 31 states have already made common sense part of their constitutions.
Unless we make it an amendment to the US Constitution, you can count on the SCOTUS to eventually overturn every State Constitution so amended.
Count on it.
You are absolutely right. This must be enacted at the Constitutional level or it will simply be overriden by the next activist Court. With 31 (likely 32) states already on record as supporting a man-woman definition of marriage, it should be possible to align another 7 states and amend the Constitution. But it has to be soon; the loons are gaining ground.
