When you start with flawed assumptions, you will never get an accurate solution. The hypothesis that vicious and systemic oppression of females since birth is keeping them out of Computer Science is hardly sound. While there may be an element of discrimination in all professions that tend to be dominated by one sex, I think it's time to look a little more closely at the situation.
Humans are a sexually dimorphic species. This means that on a genetic and physiological level, our sexes are distinct barring genetic anomalies such as Klinefelter syndrome and other rare conditions. Now as with anything that deals with biology, there is a massive amount of variation within each classification category, i.e. sex. This being said, we can and have done studies measuring the distribution (mean and variation) of tendencies for both sexes to find that they are quite distinct at a physiological level.
This means that when comparing the mean male adult brain to the mean female adult brain, the neural architecture is quite distinctly different. This has natural consequences in our behavior, predispositions, illnesses and life outcomes.
For example, it is found that the mean male does better on visuospatial tasks than the mean female, whereas females tend to do better on verbal tasks. Now all the usual disclaimers apply about cognitive testing biases and sample populations, but there is a slight empirical difference.
This is why in certain Nordic countries which pride themselves on being the most sexually egalitarian, the polarization of traditional careers is at a record high. For example, comparing two equally lucrative professions, on average men tend to study engineering and females tend towards nursing. As these countries have worked tirelessly to eradicate discrimination from their education, social, legal and professional systems, the only variable left to control for is personal preference which tends to gravitate towards sexual averages.
In conclusion, I find it often helps to frame a problem from an empirical point of view before assuming the cause and prescribing a treatment a priori.
Now, are all the developed countries in the world at the level of the Nordic countries in terms of sexual egalitarianism? Most likely not, though I doubt they're exactly Saudi Arabia either, which some of the more radical pundits tend to vociferously imply publicly at every opportunity.
Empirical and rational thought are gifts left to us by our ancestors after thousands of years of toil. I find it disappointing that we constantly fall into these irrational situations simply due to knee-jerk emotional outrage over perceived injustices. I hope one day rationality and empirical thought become the core education platform for mankind.
