That all depends on how warped your understand of marriage is.
Marriage is a contract. Nothing more.
You don't have to be different sexes to enter into contracts. You don't have to love each other.
Marriage is a contract. Quit making it more than it is.
Well I like your strict interpretation of the situation. So you'll be interested to know that the adults involved are not the only beneficiaries (parties to) the marriage contract. In Obergefell, they said children are beneficiaries (parties) to it as well.
But of course that is not what Obergefell said.
What Obergefell did say was that denying marriage to gay parents- harmed their children.
Why do you want policies that you know would harm children?
