I think it's quite rational to point out that people have psychological and physiological reaction to "inclusion" and attention. The reaction that people have may not be inherently rational, but identifying it seems quite rational to me.

Now, the way that quote is phrased is not in a rationalist manner, and Rich may not be entirely rational about it: she seems to be saying "this is what it is" without analysis or potential solution. It would take a good strong rationalist to be able to be in the situation Rich describes and not feel marginalized, since the reaction is probably an instinctual one.
