a) we don't have enough thinking on this topic.
b) the ways that anarchists tend to respond reflect both an overestimation of authority (or ability), and a lack of sensitivity about context (like the rest of the world, unfortunately).
the most common actual response by anarchists to something really problematic is to ostracize. this is certainly a solid response theoretically (the ability to associate with who one chooses is pretty basic for anarchists), but it is also quite consistent with a tendency in today's culture to cut off relationships as the only way to deal with conflict.
anarchists do agree that whatever consequences result from messed up behavior, we don't want to mirror this culture's models: police, prisons, judges, lawyers. among other reasons, because these components are based on concepts of morality, and are prone to throwing people away and denying our commonalities.
but rejecting what we don't like doesn't mean that we know what to do instead, or that we are capable of changing our behavior in practice even when we identify a better way.
