From the article:
Christopher Rufo, a right-wing provocateur who helped instigate both the panics against “critical race theory” and against L.G.B.T.Q. educators in schools, has openly said that he hopes to destroy public education in the United States.
“We are right now preparing a strategy of laying siege to the institutions,” he said last November in an interview with my colleague Michelle Goldberg. In a recent speech, delivered to an audience at the conservative Hillsdale College [Betsy DeVos is a major donor], Rufo declared that “to get universal school choice you really need to operate from a premise of universal public school distrust.”
So according to Christopher Rufo, the real goal is "universal school choice", and the method is the attacks we've been seeing against public schools.
