That’s an interesting question, HabFan410.  I’m not sure what to make of the reality of micro-aggressions.  Many people seem to think that it is an invented term that serves to promote a culture of victimhood.  Thus, people see the young black man who takes serious offence at a joke alluding to the history of slavery as overreacting.  “It’s just a joke; get over it; don’t be a victim,” people say.  The theory of micro aggression, as I understand it, says that constant exposure to such “jokes” has a cumulative effect on a person’s wellbeing.  Is that a real phenomenon?  I’m not sure.  I haven’t studied the issue.  But I have noted that some of the same people who ridicule the theory of micro aggression in minority groups tend to express sentiments of victimization concerning discussions of “white privilege.”  Many people seem to be saying, “I’m sick of hearing about the evils of racism.  Can we just shut up about it?”  Is that perhaps evidence of the reality of micro aggression?
