Of course he believes it. Most highly educated people believe the mantras they've been taught to believe
Being highly educated isn't incompatible with being an idiot.
Mostly it's an attempt to redefine sex, though.
But he doesn't actually define sex at all. Which is part of why I think he's being dishonest.
If "sex" actually meant a quantity derived from summing up "all the traits relevant to sex" which he listed as bullets (e.g. one point for SRY, one point for testicles, one point for wearing y-fronts, etc.) then we'd actually have a bimodal variable along the x-axis.
Sure. But he doesn't actually do that. He never says what the axis is at all. No attempt at constructing an actual axis is made. If you had such an axis, then one of the results is that you've find a lot of trans identifying males would still end up solidly on the "male" side. I don't think the purpose is to actually establish a continuum of sex that we can use to evaluate people, but just to muddy the waters.
I wouldn't give you that given, especially considering the target audience for SBM.
SBM seems mostly aimed at countering alternative medicine. But the trans issue has nothing to do with alternative medicine. And his article has nothing to do with evaluating evidence standards for anything to do with the trans debate either. Nowhere in his article does he ever touch on questions of scientific evidence for trans treatment or trans policy.
And the target audience is probably just credentialled medical professionals. They have a vested interest in opposing alternative medicine that's independent of any actual principled skepticism. Skepticism and self-interest happen to align on the issue of alternative medicine, but they
don't align on the trans issue. Which is probably how you end up with such an
unskeptical and
unscientific article in a source nominally dedicated to both.
Call me old fashioned, but it seems much more productive to me to address arguments rather than motives, assuming that we are trying to converge on the truth.
You would be right if I were trying to converge on the issue of whether or not sex is binary. But I'm not, and I wasn't, and that's a misunderstanding on your part. I was engaging with p0lka over the issue of how the public policy debate works, specifically in regards to whether relabeling bathrooms as "female" instead of "women" would help settle the issue. And on that question, addressing motive of participants is absolutely relevant, far more relevant than whether sex is actually binary or bimodal.
