A superficial look at the statistics re: domestic violence would lead one to believe that it's more prevalent among lower s.e.s. couples.  However, it's far more complicated than that.  Domestic violence among working class couples is far, far more frequently addressed with police involvement and, therefore, becoming a statistic.  The same violence in "suburbia" is more likely to go "unreported" and to be addressed through the involvement of counseling, clergy or other "non-governmental" means, which do not become those statistics.  
  

Domestic violence is, indeed, a problem..a huge problem, for all of us in our country today and we need to all be willing to talk about it.  It sounds like Mr. Pierce meant well as he tried to do so, but, unfortunately,  his foot got in the way.  

I'm not a Pierce supporter, but I do think Ms. Kafka's departure looks like a bit of unnecessary self-serving "grandstanding" on her part.
