No. Members of the alt right today have committed or attempted to commit pre-meditated murders/attacks. Just recently an alt righter was captured trying to blow up government buildings.
This is similar to the terrorism that the communists and anarchists committed in the 1930s.
What about the "alt lefter" who shot up the congressman softball game?
Face it, violent extremists exist on both sides. For whatever reason, you only like to point out one side.
