OK, but the gulf between that and "there is some genetic differences between the sexes" is still so large that you'd need a powerful telescope to see from one to the other.
As much as I disagree with your overall viewpoints, I'll agree on this one you have here. For a lot of individuals, the gap that you mention is huge such as to not have an immediate, explicit effect, and for one particular reason:
Something as simple as validating and completely "accepting" the notion that "there is[sic] some genetic differences between the sexes" requires individuals to throw out entire swathes of subsequent ideas/notions/etc, if we were to be logical about things. I.e. You now have "Men and women are equal but ..." or "Men and women are equal except when...", instead of the pure and logically consistent "Men and women are equal".
If you ask me, the entire thing (sex-differences topic) is starting to smell full of tiny errors and corner-cases. Perhaps we're on the verge of a paradigm shift happening once people clarify their ideas, without exceptions and acceptable-errors:
Equality isn't about people being literally identical. Nobody actually believes that. There are troubling facts like how men as a rule have a really hard time becoming pregnant that nobody denies.
Equality is about equal treatment. It's about judging the individual on their own merits, not some group they happen to belong to. "Men and women are equal" doesn't mean women are equally muscular and men can have babies. It means that when writing a law, selecting an employee, or counting a vote, you don't change your approach based on whether the person is a man or a woman.
There is nothing wrong with saying, for example, most of our warehouse workers are men because more men are able to do the heavy lifting required. There's nothing unequal about that. What equality demands is that you never say, I will not consider you for a warehouse job, regardless of your actual strength, because you are a woman and all women are too weak for it.
