It would, for one, spare us this homosexual “marraige” nonsense and all the related crap that descents from it.

Moreover, that something is actually not approved of at least sets the tone of the conversation away from licentiousness. There is something to be said about a society that at least makes a pretense of valuing virtue rather than one whose attitude is “oh hell yes!” when it comes to engaging in wickedness.
You have a point there. We do have a pop culture who reveres animalistic behavior.
But nothing will get gay marriage back into the toothpaste tube. Too many Gullibles in the world have bought that as a human right.
