It seems to me the white guilt movement uses the ideas and tactics of the Christian Churchbto denigrate, humiliate and shame individuals, but in so doing create a mediated means for them to be absolved, temporarily at least, of the shame those who run this operation do so much to inculcate. They create the disease so they can gain the power inherent in being able to administer the cure.
This is no more humanistic than Christian efforts to paint us all with Original Sin, and then claim sole ownership of the means to redemption, as the Catholic Church did and does.
It is all a very old story, told by cynics to nubile minds, and all with an Empire as an aim.
