Hiring practices are still unfair, and when it comes to eradicating biases — whether racial or gendered — there is still a very long way to go. The last thing women (and other marginalized people) need is to get explicitly left out of the running altogether. And while Title VII of the Civil Rights Act allows companies to discriminate on the basis of religion, sex, or natural origin in instances when these factors are a "bona fide occupational qualification reasonably necessary to the normal operation of the particular business or enterprise" — which is how businesses like Hooters have gotten away with hiring only women — it's uncertain whether this Act had any bearing on Facebook's decision to run these ads.
