>> So what is so wrong with making a curriculum more attractive to women?
It depends what you mean. I agree the learning environment should be gender neutral, and changes to make that happen are of course good. But you're talking about the curriculum itself, i.e. the subjects being taught. There is currently absolutely nothing in the subject matter itself that makes up Computer Science (math, logic, algorithm design, AI, etc etc) that is inherently gender-specific (unless you start considering the inherent gender-specific differences in mental skills between the average mens and womens brains and yes those differences really do exist).
By introducing gender-specific changes to completely gender-neutral subject matter you cannot help but make gender and sexual equality more of an issue not less.
Remember the road to equality is to keep the opportunities equal, not force equal numbers of both genders to take those opportunities. If you create additional artificial advantages that only benefit one gender, even if it is to address some perceived imbalance, you're just making the problem worse.
