Actual research shows that humans are anything but pentadactyl. However, 99.9% of them are, which is why it’s not hexadactylophobic to sell only five-fingered gloves. However, that’s not the only reason the SciaAm article is stupid. Not only do the overwhelming majority of humans display normal sexual dimorphism, but the overwhelming majority of transgender people do not display intersex traits. So what has their dubious “sex is anything but binary” claim got to do with anything anyway? The transgender lobby itself is very clear that sex and gender are different things … except when articles like this intentionally blur the distinction in order to provide faux scientific justifications.
Trump wasn’t trying to define gender that way. What he was trying to do was define those laws that have traditionally discriminated on sex to continue to discriminate on sex without confusion by neologisms on gender. The comments on that article are broadly more sensible than the article itself. If we want to define a whole new category of discrimination based on “gender”, let’s do that without confusing the traditional association of gender with sex. As one commenter said:
Enough already. When I was in medical school, this was simple. As a practicing OBGYN, it is still simple. We are born boys and girls, XYs and XXs, with penises and vaginas. This is determined in utero by SRY genes and mullerian inhibiting factor … the rest is purely in the presentation.
Stating that anatomy is disconnected from gender is absurd, and it leads us down a rabbit hole of linguistic obfuscation and ideologic incoherence. As doctors, we work within a biological framework not an ideologic one, and we should not confuse the two.
