All I can figure out from that comment is that you don't like their progressive bent.  I find much of the mini-aggression stuff silly, and tend to see it as counterproductive, because I think that ideas should be challenged at the university.  But I understand that it's a reaction to prejudice and hatefulness of all sorts.   I have been out of academia for a good long while (being an adjunct does not really count), and my brother (who is a college prof) tends to take a dim view of all of that, so I really have no idea what discussion or thought went into it.
