Sex, Gender and Neo-Marxism, By Mrs. Vera West

As documented by David Haig, "The Inexorable Rise of Gender and the Decline of Sex: Social Change in Academic Titles, 1945–2001," Archives of Sexual Behavior, Vol. 33, No. 2, April 2004, the term "gender" was once rarely used, even in academia, but that changed with the work of psychologist J. Money on the sexual identity of hermaphrodites, rare occurrences of birth defects where individuals had ambiguous sexual characteristics. Money then distinguished between sex and gender, with sex being the physical characteristics and gender the social identity.

Psychologist Robert Stoller, working with transsexuals, developed the idea of "gender identity." The radical no-Marxist feminists then took this work further in their critique of sexual relationships in the "patriarchy." And the rest is history, with the deconstruction movement now devouring feminist children of the revolution with the trans agenda, with the question of "What is A Woman?' being now unanswered by the chattering class of today: https://www.dailywire.com/videos/what-is-a-woman

It was never about liberation, and all about the will to power of elite groups.

From the Haig paper:

"More than 30 million titles of "academic" articles, from the years 1945–2001, were surveyed for occurrences of the words sex and gender. At the beginning of this period, uses of gender were much rarer than uses of sex, and often used in the sense of a grammatical category. By the end of this period, uses of gender outnumbered uses of sex in the social sciences, arts, and humanities. Within the natural sciences, there was now more than 1 use of gender for every 2 uses of sex. The beginnings of this change in usage can be traced to Money's introduction of the concept of "gender role" in 1955 (J. Money, 1955). However, the major expansion in the use of gender followed its adoption by feminists to distinguish the social and cultural aspects of differences between men and women (gender) from biological differences (sex). Since then, the use of gender has tended to expand to encompass the biological, and a sex/gender distinction is now only fitfully observed."
