Imagine a situation in which ALL the facts were reversed.  BLM holds a legal march chanting "what do we want? Dead cops. When do we want them? Now" or an anti Trump rally happens and Madonna muses about blowing up the White House.  Other than the reprehensible things they say, its a legal protest.  They have a permit.  Most of the protestors are civil.  Then the alt right shows up dressed in black carrying baseball bats and looking to cause a fight. Many fights break out.  Somebody on the left upset his rally has been taken over does something really stupid and someone on the right is killed.  The media demand Trump denounce the alt left.  He says (after a couple of days) that they are horrible horrible people and have no place in America and then goes on to say that the alt right are not totally blameless.  There was violence on both sides.  The media are apoplectic.  How can he support the alt left when it was someone on the right killed? I'm convinced the media bias is helping Trump
