&quot;The significance of the historical roots of Political Correctness cannot be fully appreciated unless Betty Friedans revolution in sex roles is viewed for what it really was  a manifestation of the social revolutionary process begun by Karl Marx. Friedans reliance on Abraham Maslows reflection of Frankfurt School ideology is only one indicator. Other indicators include the correspondence of Friedans revolution in sex roles with Georg Lukacs annihilation of old values and the creation of new ones, and with Herbert Marcuses transvaluation of values. But the idea of transforming a patriarchy into a matriarchy  which is what a sex-role inversion is designed to do  can be connected directly to Friedrich Engels book The Origin of the Family, Private Property, and the State. First published in 1884, this book popularised the now-accepted feminist belief that deep- rooted discrimination against the oppressed female sex was a function of patriarchy. &quot;
