Thanks for your points. Excellent. Let me add one more.
It is vitally important to also make this clear:
6. This Amendment doesnt "ban gay marriage" as the media would have it. The Amendment *preserves* the current and long-standing definition of marriage from adulteration through inclusion of gay unions, which are manifestly not 'marriage'. This definition of marriage has been in western law for millenia, encoded in Justinian's Laws for example.
Earlier than that... Genesis (1:27, 2:18).
