There is a giant straw man argument in the room. Nobody is arguing that women should be discriminated against.
The real argument is more like this:
Aggregate data show that men and women generally have different traits. Those traits lead to different choices. Those choices explain the aggregate differences in the numbers of men and women in different occupations.
Therefore, it is unreasonable to conclude that statistical disparities between women are the result of discrimination. Efforts to increase the percentage of women in jobs they don’t generally like, or are not generally suited to, are either futile or harmful.
As an aside, I note that few feminists ever remark on the fact that over 90% of workplace fatalities are men. Nobody seems concerned about the “death gap.”
Bottom line: if you simply leave men and women to make their own choices, and hire solely based on qualifications, there will be some jobs that are predominantly female, and others that are predominantly male, and there is absolutely nothing wrong with that.
