Everyone knows that Harvard is Satan’s Vatican and that it issued special Holiday Placemats For Social Justice.
Rod Dreher gives some helpful advice to families trying to cope with their social justice warrior children ruining Christmas with their obnoxious “talking points.” Dreher recommends you go full Cartman:

When your Harvard undergraduate comes home for the holidays and undertakes to preach about politics at the dinner table, ask yourself, “What would Eric Cartman say?” Then say it over and over again, until the SJW runs sobbing from the table.

Harvard has since apologized for it’s risible placemats, but remember this, the Devil is the Father of Lies.
