Trump called it like it is.  I respect him greatly for refusing to do what the media demands that he do.  Many politicians would walk in circles and twist in a pretzel to kiss their own butt if the media demanded it.  There was a permitted protest regarding the removal of a confederate statue.  As Trump said, many at the protest were simply people who do not believe in modifying history to please the current fad.  The media, of course, out to sensationalize talks about Nazis and KKK, etc.  The purpose of the demonstration was not bad, i.e. they objected to the removal of a statue.  Many in the country would agree.  Other groups attempted violently, apparently, to prevent the protesters from exercising their first amendment right to express their opinion on a proposed public action.  Trump was exactly right to condemn violence and extremism from every source.  The so-called Nazis and KKK are likely very very happy that the media highlighted and legitimized them.
