The problem with throwing mud indignantly, especially when indignance is justified, is that emotional mud splatters over everything.  It's difficult for the muddor to define all the muddees.  Emotion doesn't think.  It just spits mud.  And now, I don't think Coulter meant to open the door for the innocent dachshund-legged passenger to potentially tweet about Coulter's horse mug.   Women hate horse face comparisons.  Such a tweet will probably crescendo ever so much greater on the rebound.  Auwe.
