A policy that provides benefits (e.g. university enrolment) to some student candidates only if they sign a 'covenant' is exactly the definition of coercion (sign or else) and constitutes both discrimination on the grounds of sexual orientation and intimidation. Signing a covenant under duress cannot be said to indicate voluntary agreement.

It clearly, obviously and illegally impacts the rights of LGBTQ students by denying them university entrance (purely for the reason that they would not agree to surrender or suspend their legal rights), and is very much a material infringement on their rights. To pretend otherwise is disingenuous and results in an unsafe ruling by the lower courts (which planet are they from?).
