Trimming for brevity...
Well, partly because you have pretty much stripped away all the cultural meaning of "woman" beyond her mere physicality.
...
If there is no more to "woman" than mere physicality, why should I care whether not having been born with a penis prevents women from doing well in sports any more than if another women was born with genetics so she wasn't ever going to be tall enough to make the basketball team. It's all just mere materialist physicality.
...
Certainly not, but if you reduce being a woman down to nothing but the physical fact of producing ova, it's not clear to me that it's a category worth protecting. My conception of my wife as a woman involves the ability to produce ova, but in a more transcendent sense in terms of the connection to cultural ideas associated with fertility and nurturing and all sorts of other connections and associations. Yes, at the root of it there is physicality, but if you reduce it to just some materialist thing about ova I think you've thrown away what everybody actually cares about.
Your desire to do away with the associations between the sexes and the cultural instantiations and markers of the sexes reduces women to just being people who happen to have ova. Like I say, who really cares about defending that deracinated category?
I think you're taking it to a much more extreme level of materialism than any of us actually hold. The fact that we are evolved to produce ova and sperm is incontrovertible fact. But with that evolution comes many other dimorphic differences - and those differences aren't going to magically disappear if fashion changes to be unisex.
Part of producing ova in humans is the very long period of gestation, as well as the very long period of prepubescence that requires care for our offspring. And that burden is borne almost entirely by females. We would love to have more male help with childrearing, but at the end of the day, there's no expectation from feminists (excluding some very fringe anti-man types) that the burden would be equally distributed. Taking the position that there should be no
social barrier to shared child care is not the same as insisting there will not be an
evolutionary tendency to childcare in one sex more than the other.
The ability to produce ova or sperm are also tied to several other physical traits, which also don't just evaporate when fashion changes. Males will continue to have wider shoulders, and relatively narrower hips, and facial hair. Females will continue to have higher body fat percentages, wider hips, a tilted pelvis, and boobs.
I'm not imagining some "utopia" where half the males wear dresses and half the females wear dungarees and weld stuff. That's not a reasonable outcome, and it would require a fundamental alteration to our species. Sexual signaling will still exist, and it will still be subject to cognitive manipulation. Even if you reduce the western social pressure for seven-layer dip type facial make up in females... you're *still* likely to end up with a large number of females choosing to darken their lips and smooth their skin. It mimics the physical effects of ovulation and youth, and are attractive to males seeking a mate - even if none of the people involved consciously know that's what they're doing. Most males will very likely still select clothing and outfits that accentuate their shoulders as sexual indicators of virility and strength.
What I'm after is the removal of proscription, not the implementation of prescription. Something not being socially prohibited doesn't necessitate that it be socially obligated.
Think about it in the same general frame as negative versus positive rights.
Honestly, is Rolfe's objection to men in women's changing rooms just about ova and sperm....? Thousands of years of cultural accretion and meaning are being reduced down and trivialised.
Lol, I'm sorry, but I really think this is a very male take of you.
In the sense of having boiled this down to a layer of scum on the bottom of the pan... yes, it has to do with ova and sperm. More realistically, however, it has to do with the inherent natures of males versus females. It has to do with the inherently higher levels of physical and sexual aggression demonstrated by males of the human species across all known times and geographies. It has to do with the physical and reproductive vulnerability of females to predation by males. And it has to do with the evolutionary tendency of females to cluster for safety and protection, to interact more directly with each other, and to seek solidarity with other females when they are particularly vulnerable.
At the end of the day, yes, ALL of that has to do with the production of ova and sperm. It has to do with the evolutionary adaptations our species has made as a sexually reproductive dimorphic species.
Almost every known culture throughout recorded history has had some element of female-only spaces. Even the most regressive cultures, where females were literally viewed as property, had female only spaces where males were not allowed. Spaces where we menstruate, where we miscarry, where we give birth. Spaces reserved for "female mysteries", rituals, and sacraments.
