I've edited your original opening paragraph because the way you came across is biased and overly opinionated. If you are trying to make scientific points, you should make them with logical language choices.
I work in academic science research and some of the best PhD students and post-doctoral researchers I have encountered are female. They are brilliant at their work and as good as males.
I believe there are differences between people that are, in part, based on gender, but it's not the most significant factor. Promoting female engaging with STEM subjects is a course-correction that will see greater rewards over time. You can't put more money into STEM now and expect everything to be fine 5 years later. These are cultural and generational changes, and will take time.
The "male brain" and the "female brain" are points on a spectrum, rather than binary poles in opposition. Think of it as a bell-curve distribution of "male brainness" that overlaps with "female brainness".
I agree with the push towards inclusion of females within STEM subjects, because there are many many females who are as capable as males of doing an excellent job, and who enjoy the work. So why not encourage them to learn it?
In addition, I have witnessed first-hand multiple examples of male bosses treating females differently, and actively trying to push them out of the course/subject. Needless to say, HR got involved, and are getting involved, but these attitudes exist and are prevalent. In my line of work, right now, in 2018, males are treated better than females, regardless of the quality of the science.
