> Affirmative action is not only legal, it's required in academia if a university wants federal funding.

Yes, but what many people stereotype "affirmative action" as being, or at least including -- notably, including the upthread suggestion characterized as "let's just hire only women for a while to balance out the numbers" -- is not only not required even in that context, it is quite illegal (and would be equally illegal if, say, "blacks" replaced "women" in the description.)
