Trump is also a symptom.  His approval ratings haven't changed that much, still about 41% and the strongest support is in the electoral areas that critics can do nothing about.  One poll in Virginia tells us that the same % that blames the Alt right for the Charlotsville violence is balanced by those who believe both sides were equally at fault.   Republican voter approval is well above two thirds.  One factor here is that a very large portion of the country believes that the alternative (Hillary/Pelosi, Democrats, etc) are worse.
