The main issue I see with your argument is that you're supposing interest to be correlated with anticipated ability and enjoyment of the profession.I'm not, I'm suggesting that a set-up that prefers those with a natural inclination or enjoyment/ability of a particular field should not be undermined in favour of those with a possible passing fancy.
If the system is detrimental to those with skill/enjoyment/inclination based on a particular set of their shared minority traits, this might be a problem in need of correction.
Unlike French Fashion trends, programming is an important driver of our society,
Whether something is important to our society or not should make no difference in correcting inequities in opportunity.
There's no way of knowing that when most women do not even take an introductory programming course.
The assumption here is that there is a large pool of women waiting to take courses that are being discouraged. I see no evidence of that at all, and that's what I'm questioning.
