Did I say that???  Are you being deliberately obtuse?  Are you, like trump, a neo-nazi apologist?

Yes, there are extremists on the left also.  No one is saying there are not.  But the vast majority of violence committed have been by right-wing extremists.  It's not even close when it comes to acts of murder.  A study by the anti-defamation league revealed that there were at least 372 murders committed by domestic extremists between 2007 and 2016.  Of that number, a whopping 74 percent were committed by right-wing extremists, 24 percent by muslim extremists and about 2 percent by left-wing extremists.  Is that clear enough for you?
