I still can’t tell whether you’ve understood my point?

It is dangerous to downplay differences which exist, whether it’s between sexes or within them. For instance, a fair bit of medical practice is well-tailored to men and poorly-tailored to women precisely because people were thinking “oh, it’s all the same, doesn’t matter, and we’re already set up to do this on men”. We’ve spent a lot of time over the past 20–30 years compensating for this incorrect assumption of uniformity, and there’s still work to do. The previous outlook mostly wasn’t been driven by the idea that women aren’t important, but rather than the differences are unimportant.

Well, oops! Turns out that sometimes the differences are important enough so that you should recommend different treatment or diagnostics starting out, even if thereafter you’re going to be responsive to how the patient is responding, what tests show, etc..
