Masculinity The impetus for the thread began with the practical question of gendered bathrooms. Or, at least, that's how I'd put it -- the other side puts it sexual bathrooms, and holds that gender and sexuality are, if not identical, at least a tight fit, such that we can utilize sex in place of gender with respect to norms of bathroom usage. My counter-point has been that we have never used sex in place of gender, but rather the emphasis on chromosomal patterns is a novel interpretation of the traditional gender distinction - we already knew who the men were when we pointed out they had XY chromosomes. We didn't identify men from their chromosomal characteristics, but rather discovered a possible biological distinction from science which could possibly support the traditional gender bi-section, at least as a rule of thumb. (as it turns out, though, as is almost always the case in science, the picture is much more complicated than all that)
We can describe gender outside of the parameters of sexual characteristics, and we in fact do so whenever we describe a behavior or a tendency of a particular gender expression(Boys will be boys!). Further, individuals show that the sexual characteristics are in no way determinative of a person's gender, given the diversity of genders. In fact there are people who "pass", to use the straightforward but still sad term -- there are already people with different chromosomes than the traditional view of gender would predict but who are able to utilize the facilities they would prefer to use. As such I submit that we do not actually use sexual characteristics to police gendered spaces, but gender, and that gender is much older -- and more practical -- than chromosomal identifiers, given that we do not actually investigate the genome of most people we know.
So, at a minimum, we should address what we mean by gender given that this is the actual rule we use in policing.
The above should be enough to say why I think you cannot support the sex-gender link empirically. People will point out that chromosomal differences are small -- the oft-cited 99.5%/0.5%. But there are so many more genders than even these three possible chromosomal arrangements. There's the four-gender theory I pointed out which gets at a richer expression of what gender is, but it's a bit too abstract for my taste: good for research, but bad for really understanding a particular gender identity in its depth. Which is what I think a lot of this hasty generalization does is attempt to come to some conclusion based upon a small amount of evidence on a topic that, in fact, is incredibly complicated and even difficult to determine in a manner that's not merely a personal reflection on one's own life and gender. So we shouldn't be all that surprised that the traditional view of gender, a quick-and-dirty distinction that's easily filled in with the details of one's personal life so that the partner is the other gender and you complement one another, is empirically inadequate to the task.
That leaves a values approach -- which I'd say patriarchy hasn't really done all that well for itself. The pleasures of patriarchy are the pleasures of power rather than the pleasures of self-sacrifice, as the story is told. Puissance, not protection is the only rational ground to support it. That should be fairly obvious that power for its own sake doesn't exactly pass the ethical bar, or at least, not very many of them. So that leaves an aesthetic grounding -- a non-ethical value. I think most gender-identities fall into this category: they are personally rewarding in that it feels good when we do what feels right to us to do.
But in contrast to the ethical violations of patriarchy I don't think that the aesthetic grounding of traditional masculinity as provider-protector-owner of the family is strong enough. The ethical violations are seen in the statistics of violence against women. If patriarchy is not the reason -- it doesn't exist, or is a dreamed up excuse of a few political radicals with their noses in too many books -- why is it that women are disproportionally subject to violence in intimate relationships?
That is -- in setting out the traditional view of gender, given that we should set out the actual rule we use in policing gendered spaces, I think we lose any attraction said view may have. So even its aesthetic grounding is questionable.
As such I'd submit that such a traditional view of gender ought not be used in public, at least. And public restrooms are certainly public. But the public is for everyone, not just 99.5% of the population, and just because some families like to live a romanticized vision of the traditional model that's not a reason to block people from shitting in public where they'd like to.
