I know some old Freepers will mention the right to associate business with who you choose and that’s fine, but just imagine if women were banned, just imagine the outrage, also this is a state university so even if freedom of association were to apply it cannot apply here for this is a state institution.
Why would freedom of association not apply at a state institution? Did you mean a private institution? If you did, the fed uses student loans to force Title IX rules to apply at private schools.
Equal protection and due process would trump right to associate if you want to maintain the courts’ premise in the last 70 or so years.
