1. A university is an institution with circumscribed responsibilities which engages in a contract with its students. Its main responsibility is to provide them with an education. It is not an arbiter over their lives, 24/7. What they do on their own time is none of the university’s business.
2. One of the essential values in higher education is that people can differ in their values, and that these differences can be constructively discussed. Harvard has a right to value mixed-sex venues everywhere, all the time, with no exceptions. If some of its students find value in private, single-sex associations, some of the time, a university is free to argue against, discourage, or even ridicule those choices. But it is not a part of the mandate of a university to impose these values on its students over their objections.
3. Universities ought to be places where issues are analyzed, distinctions are made, evidence is evaluated, and policies crafted to attain clearly stated goals. This recommendation is a sledgehammer which doesn’t distinguish between single-sex and other private clubs. It doesn’t target illegal or objectionable behavior such as drunkenness or public disturbances. Nor by any stretch of the imagination could it be seen as an effective, rationally justified, evidence-based policy tailored to reduce sexual assault.
4. This illiberal policy can only contribute to the impression in the country at large that elite universities are not dispassionate forums for clarifying values, analyzing problems, and proposing evidence-based solutions, but are institutions determined to impose their ideology and values on a diverse population by brute force.
