I'm of the impression that women select out of certain fields because they have different priorities; if you're proposing pushing more women into a career they evidently don't want, I think the burden of proof is on you that women are, in fact, socially corrupted in a way that pushes them or of tech. If there is a bias against women, we absolutely should fix it, but I don't like how our society assumes all gaps are necessarily attributable to bias pending damning proof to the contrary.
Besides, men and women have had distinct gender roles (and largely the same roles) in every society since before history; while (or rather, "because") I support women's rights to do whatever they dammed well please, it seems unlikely to me that we discovered in the last fifty years that that was entirely an ancient conspiracy to make women miserable, and thus we should push women into the careers we know they want (never mind that the evidence points in all different directions) even at great expense to the industry.
Anyway, the question isn't "should we force women to be programmers or housewives?". It's not a dichotomy and we shouldn't be pressuring anyone into anything.
