Yeah, I hear that same-sex marriage will destroy everything some Americans hold dear. How exactly, I've yet to have explained.
I think what
is the more appropriate question. The notion that anything of value will be lost if you allowed people to marry whom they love is preposterous. If you are not one of those people, you might not even notice it. If you dislike them so much, you will never attend, let alone participate in it, so what goes behind the wall of that Church that you're so terrified to enter will remain forever inconsequential for you, without as much as brushing past your life.
But much more importantly, if these are the people that you have a problem with, your priorities about the world around you are way off. With all the terrible things that people do, having a problem with two people expressing and celebrating their love for each other in the same way as all other people do is somewhere at the bottom of the list.
