Chris Matthews is rude.  Why?  He represents a denigrating public discourse, a condition almost, but not quite, a century in the making. 

‘May I complete a sentence?’ 



‘Because I’m talking.’ 

‘But I have to say, you misrepresent what I’m saying, what I mean…’ 

‘Did I give you permission to speak?  No.  But go ahead, answer the question I’m answering myself while talking over you as you answer my question.  Ha!’
