"The point is that Mr. Trump has done the morally indefensible."

I fully agree with this statement.   That said, I believe Trump has not put a "final nail" in his own coffin.  As he has done since the start, he is talking around the media.   I've been spending time on Facebook reading comments that support Trump.   The common thread in their comments is Trump is speaking the truth about BLM and Antifa coming to the demonstration equally prepared for a fight.   His supporters ignore the moral difference and buy into the false equivalence between the radical left and right, they see BLM and Antifa as repugnant as the KKK.  

He is stating a fact that some parties on both sides were looking for a fight.  For the most part, the media is ignoring that small grain of truth.  Trump supporters position their arguments as a defense of the right to free speech and expression. 

I fear this is fast becoming a wedge issue that will divide America unlike gun rights or others.
