As a (weak) Harvard affiliate, I have to say that grandfather clauses have extensive legal precedent, and have extensive case law supporting their use from 1890-1910, many argued by Harvard graduates. Indeed, similar clauses were commonly included in many state constitutions at the time. If there is racism here, Harvard has long since paid the necessary reparations. Harvard set aside $100M, or an entire 0.2% of its endowment, to pay off any racial harm it has done. It did so after an in-depth analysis about the value of the lives it has impacted, and the relative value of those impacted and those impacting. Indeed, it's clear there's nothing to see here. Carry on.
