Please provide a short summary of the essay titled, Postscript: Contempt as a Virus, from the collection, Intimations?

Postscript: Contempt as a Virus creates a metaphor in which Smith equates contempt as a virus, infecting increasingly more people in American society as ideological and political differences consume daily life and entrench mistrust of the ‘other.’ In particular, Smith focuses on the killing of George Floyd as an example of the way in which contempt as a virus can have deadly consequences, in particular for those groups who have endured such hatred for centuries.
