This is so ignorant you must be living in a bubble.
There are a huge number of barriers against girls and women. Men are more likely to get interviews, once interviewed they're more likely to get hired. Once hired, they're more likely to get good positions and promotions, not to mention higher pay. In the workplace, women face discrimination, sexist comments, and slurs. They are still a small minority of coders.
Most males are totally blind to the obstacles women face and take the status quo as akin to the "natural" state. They conclude women are just inferior. But they aren't.
Calling this plan "the politically correct form of sexism" is classic doublespeak. If you had a shred of awareness, you'd understand this was the opposite, it's a tiny attempt to *correct* institutionalized sexism.
