And what if the person they love, want to marry and spend the rest of their life with, happens to be the same gender as themselves?
No law is stopping them from loving each other and spending their life together.
btw, unlike President Obama, I'm actually perfectly fine with gay marriage.
I leave it up to the State's to decide...if the people there want it, so be it. I live in Illinois. It makes no difference to me either way.
