I divorced my wife of 20 years a few years ago. We had a miserable time together, I stayed until the kids were grown up.
THEN I married my true love, who I also had kids with, who are also grown up (hey, kids, the next generation, without marriage, what a concept). I had a vasectomy before it, so according to the supreme court argument from "your" side, I would not qualify for a real marriage.
It was the best experience of my life, and every day I am more and more happy with the decision.
Without it, I'd certainly be a drag on society. I'd be costing you in taxes like you would not believe.
But as far as you are concerned, no benefit.
