I have a good friend that thinks like this too...makes her feel open minded...
To my mind, there is a huge difference between two people saying “we’re married!” and the government agreeing with it. In this country, you are free, you can make choices, and live in whatever bizarre manner you want as long as you are not harming others.
If my next door neighbor decided to call himself a car, sleep in his garage, drink motor oil, and walk around making ‘vroooooooommmmm, vroooooooooommmmmmm’ noises constantly, it is none of my business. When he goes down to the County to get his license plate, he then makes it my business. He is asking me, in the form of my elected government, to cosign his insanity. Same goes for a couple of homos or any other freakish combination of multiple persons, species or solitary genders. They can call themselves whatever they wish, but I oppose giving their insanity the legitimacy of government recognition.
