Tell that to the asian students suing harvard.
Harvard is systematically penalizing Asians on the grounds that they have lousy personalities. Of course this is almost certainly a scheme to implement affirmative action without publicly admitting to it; whether that makes it better or worse is debatable.
Again: while I am personally fine with affirmative action and see the rationale for it, my argument doesn't demand that you be OK with it. All I'm arguing is that it isn't the same as what this Japanese school did.
