How will the feminist plan of limiting men going into STEMs help women?

[Common Sense]

Limit males or not, women are now free to go into STEMs. I don't see how limiting males will create more opportunities for females.

If feminists want more women to go into these fields, why don't they limit their efforts to encouraging more young women to go into these fields. Why are they so hell bent on limiting opportunities for males?

If we cut the number of males to be proportional to females and all of a sudden there are only 1/3 the number of U.S. students taking STEM courses, what will the results be? Will this affect the market place? If males are not allowed to take the courses they wish to pursue, will this lower even more the number of males going onto college?
Feminists are pushing for a proportionality rule much like we see with sports to be placed on colleges. As with sports and the recent sexual assault change, a college not complying would be a title ix violation.

Funny how feminists and feminist supporters argue so hard for such policies, and then deny it.
