Gender Theory is the latest bit of nonsense to be foisted on the public by the Left. If there is physical sexual ambiguity at birth, only the doctor and the parents have a say. Aside from that, having been involved in some sub-cultures, they are here one day and gone the next. And this is also something that stems from Radical Feminism.
"2. Recent years have seen new approaches to women’s issues. A first tendency is to emphasize strongly conditions of subordination in order to give rise to antagonism: women, in order to be themselves, must make themselves the adversaries of men. Faced with the abuse of power, the answer for women is to seek power. This process leads to opposition between men and women, in which the identity and role of one are emphasized to the disadvantage of the other, leading to harmful confusion regarding the human person, which has its most immediate and lethal effects in the structure of the family.
“A second tendency emerges in the wake of the first. In order to avoid the domination of one sex or the other, their differences tend to be denied, viewed as mere effects of historical and cultural conditioning. In this perspective, physical difference, termed sex, is minimized, while the purely cultural element, termed gender, is emphasized to the maximum and held to be primary. The obscuring of the difference or duality of the sexes has enormous consequences on a variety of levels. This theory of the human person, intended to promote prospects for equality of women through liberation from biological determinism, has in reality inspired ideologies which, for example, call into question the family, in its natural two-parent structure of mother and father, and make homosexuality and heterosexuality virtually equivalent, in a new model of polymorphous sexuality.”
