"None of this would matter if government schools were abolished, as they should be."

Only to those who choose to send their children to the government indoctrination centers. I declined that option for the most part.
Alternately, parents can find out precisely what is being taught to their children and correct the misinformation as they see fit. I have spent considerable time in my life fulfilling my obligation as a parent to "unteach" my children some of the BS they were being propagandized into believing.
