It doesn’t. At all. And if they can find a church to marry them, have at it. Go for it. I could give a shit. But when government climbs into bed with them and recognizes their marriage, that is catastrophic. It redefines marriage which opens Pandora’s Box.
Like all progressives, you can’t think beyond the end of your nose. You actually believe that all actions occur in a vacuum.
Ah, we get to Poodles big complaint... the government actually protecting people's rights when they aren't white male and straight.
Marriage has been redefined throughout history. Marriage used to be a transfer of property- the property being the woman, who often entered an arranged marriage, where whatever she had became her husbands, and it was okay for him to rape or beat her.
Because Marriage... which is totally sacred and stuff.
Fortunately, we "redefined" the institution to give women rights, including the right to leave the marriage if it just plain didn't work.
