he’s making this way too hard
The simple definition for marriage is that it’s an institution which offers a model to society of the reproductive family unit. Marriage is all about encouraging responsible reproduction. If there was no such thing as reproduction, there would be no need for marriage to exist. It makes absolutely no sense at all for a society to encourage homosexuality or incest. There is no benefit to be had for society from those activities.
