The same people ruining public schools and using them for political indoctrination send their loved children and grandchildren to private schools.
Observe what they do, not what they say.
One reason this played out this way is the dwindling number of Americans in public schools; there is no real “next generation” of American children, so the border gates are flung open to entice a new wave of public school students. My town is “white” in terms of the 60+ age group, and heavily foreign in terms of the 40-and-under age group; it is by design.
