Dr. Jennifer Roback Morse of the Ruth Institute picks apart the incoherent position on marriage espoused by the Libertarian Party of Minnesota.

A sample:

We believe that marriage is a fundamental human right, How can you believe that, if you don’t know what marriage is, or why we need it in the first place? The essential public purpose of marriage is to attach mothers and fathers to their children and to one another.  Marriage exists to protect the legitimate interests of children, who cannot protect their own interests. Without this public purpose, we wouldn’t need marriage at all. And that is why marriage is more than a collection of individuals, and why family law is not simply a subset of property and contract law.  Alas, poor libertarians: they don’t know how to think without a contract metaphor.
