Right. Except we are not permitted to "marry" our dog, our car, our home, a 105mm howitzer, a four year old, or someone of the same sex.
If Justice Kennedy agrees that perversion is just wonderful, where's the end to this?
My own personal view of marriage (not especially popular on FR): Marriage is a sacrament, as defined by the Roman Catholic church, and then incorporated into most of the world's other major religions. It goes like this: A man and a woman make a promise to GOD and to eachother, witnessed by their congregation. ANYTHING else, including getting married by a local "justice of the peace" or by Captain Stubing on the Love Boat is, by definition, a "civil union." Therefore, if we are going to adjust our legal definition to call some guy who married a hooker he just met and took to a Vegas drive-by wedding chapel "married," who cares what we let the buttsex crowd say about themselves. If you didn't get married in a Church, Synagoge, Mosque, or Temple... You're not married. Even if the law says you are.
As far as I'm concerned, if belaboring this point helps us politically (the returns will be diminishing from here on out), than by all means keep pressing it. Once it is no longer a favorable battle, then we've got much bigger fish to fry.
For what it's worth, I have gay friends. And I tell them to their face that they are good people, but they their "lifestyle" is a mental illness.
