At first glance, this seems to imply a super-power view of defense, that you are adequately defended only if you can annihilate the other side. … Hare’s equation of defense and attack comes from two sources … [t]he general point is that ethical theories in this style can readily be seen as offensive weapons, aimed against prejudice, so that if there is an important style of prejudice that is immune to them, they are not well designed for their job and are likely to be replaced, if not by prejudice, then by an ethical theory with more firepower. To some extent, this is true of all of them, although they differ from one another in their aggressive ambitions. —B. Williams, Ethics and the Limits of Philosophy, ch. 5.
