Interestingly, you decided to frame this as "treating [the women] differently on the basis of sex". Why not "treating [the men] differently on the basis of sex"?
That's a good point, and I suppose that I did so because the blog post focused on the impact on the women of the team. It is also possible that I have some subconscious bias, and framed it as a 'women's issue' because of that, but I cannot be certain.
