Dalrymple notes that the slogan reflects the demand that
everyone join in a chorus, failure to do so being a crime.
This, he points out,
goes further than authoritarianism, under which dissent is a crime. As under the totalitarians, positive and public assent to and enthusiasm for certain propositions are required.
Failure in this regard
is a symptom or sign of being an enemy of the people. If you do not join in the chorus, but are silent, you are a racist, complicit in the killing of George Floyd and other crimes.
