Defensive Responses

Grimm gives us three examples of defensive responses to postmodern change: distancing, blaming, and helping the other become more like us. I suspect that these defensive responses still occur in many writing centers today, nine years later, but I am wondering if writing centers are even aware of them, if they have actively become conscious of these responses and who is doing them. And if they are aware of them, what do they do in order to address these defensive responses, what do they offer as a response to these responses?
