I think it helps to understand the intellectual foundation of some in the feminist movement.
Back in the 1800s, it sought a complete fulfillment of the promises in the Declaration of Independence. Its leading lights (Willard, Anthony, Stanton) were still advocating a liberal (classical), enlightenment philosophy of equality before the law.
The second-comers in the 1960s had marxist roots, a philosophy completely alien to the DoI, classical liberalism, and American culture & politics. For example, Betty Friedan was not just some housewife as she lied in Feminine Mystique. She had been and still was a marxist activist. Steinem, Dworkin, MacKinnon, & such are cut from the same marxist cloth.
Feminism from the 1960s on was little more than a marxist front-group, what the marxists call a "popular front." It was one of many PFs used by marists to influence American politics and culture.
From my perspective, I have no problem with equality before the law., as long as reality is acknowledged.
For instance, women have no place in combat units, period. Partly it is due to the physical differences*. Party it is due to the effect of women in the unit.
I signed up as infantry and went through all-male training through Basic & AIT. Comparing notes with soft-skilled men who had co-ed training, it is easy to see they were poorly served and less prepared than I**, due to the presence of women and the accommodations required. That poorer training was born out in the wash-out rate through RIP, which found very few soft skills able to hack it.
Jump school was an exercise in frustration, as PT was terrible. It was kept at a pathetic level so as to not wash out every darn female who wanted her jump wings.
When I got to my (all male) unit, the stories I would hear about mixed units were pretty disheartening, disgusting, and many other "dis" words. Men who came from those units were grateful to be here, despite the fanatical/near-psychotic discipline & standards.
* Less upper-body strength, more injury-prone, more time/money required to train up to the standard, more prone to casualty due to sub-standard environmental conditions++, pregnancy issues & the effects of a soldier's pregnancy on the unit
** "Poorly served and less prepared" can be translated as, "more likely to die if that training had to be relied on."
++ I can get more descriptive, but would rather not, as lunch approaches.
