So is our primary goal increased representation of women, or treating women well? (Put more directly, if we find that mistreating women makes more of them enter technology, what should we do?)

It's certainly possible that not as many women are interested in technology careers as men. (Seems overwhelmingly unlikely to me based on both anecdotal and rigorous evidence, but as a good scientist, I should say it's possible.) But why does that justify mistreating those women who are interested? And why should we be satisfied with our behavior based on merely being not as bad as a religion or another industry?
