Even if there were groups of people (gender/sex, race etc.) who are statistically significantly better, or worse, at something, that does not mean we should set a standard of conduct based on it, and relegate people only to roles that are statistically better suited to them.
All people should have equal access to all activities/roles, and not be prevented from taking/doing them by their gender, or race, or anything else, save by their individual capacity – and that only after they for themselves tried and could see it is incompatible with the role they have chosen, which will show itself in time. Meaning, there should not be any externally imposed conditions, restrictions for who can or can’t seek to take on a certain role, save for those that are necessary and inarbitrary to the concrete role, as for example previous knowledge and maturity (and that in itself should be accessible to anyone to acquire, be it by study, or by growing up).
So the things that are inalterable about a person by virtue of their birth or otherwise, like sex or ethnic background, should not in themselves be impediment to a person’s aspiration, but a person is limited only by their inner capacities, and these they should be capable to develop to their full extent. Because even if, for example, most women are more comfortable to take on nurturing roles, there are among them those that would prefer to do something else, and be perfectly good at it.
Whereas there are objective limitations to a person’s ability to take on a certain role, and they may to an extent even significantly correlate with a certain gender, or a certain ethnic background, the belonging to a certain group of people in itself is not what makes a person incapable of a certain act, but the concrete limitations are, which they may or may not have, regardless of their group-membership.
And also, all good works should be held equally high in esteem – in that, complementarism and equality in difference is a good thing, as ultimately people must and will take on different roles, and they should be treated equally and given the same respect and rights regardless of what role they assume, if they partake in it to the best of their capacities and in good will. But to disqualify an individual person for sake of their affinity to a group that is statistically this or other, is to fallaciously apply what may be true for a group, to an individual, and therefore to confuse the abstract (a category of people) with the concrete (an individual).
