While I’ve never read Huxley’s novel, I have to disagree with the premise of the linked article. What is occurring in today’s schools (and throughout the broader culture) is not a moral education at all, but an immoral one.
As C.S. Lewis pointed out in the Abolition of Man and Mere Christianity, There is only one legitimate set of moral values. The attempt to impose any value system which does not conform to human reason or experience is thus indoctrination; it is forcing others to agree to the concept that 2+2=5. This is not a moral education at all, but tyranny.
A truly moral education, one in conformity with true teleologically sound moral principals - not in opposition to them - is actually a good thing.
2+2=5 or another way of saying that there are more than two sexes.
It also explains why social justice is liberal political dogma, their political ideology invested with religious levels of devotion.
