Alt-right....Alt-left......both are two peas in the pod.  If David Duke asked "Are you Jewish"....an alt-left will asked "are you a hater". Then both will dismissed you for challenging their views. Personally, I think both kind of feed off each other, their agendas are so ugly that I would think there will be a support group combining the two! I am reminded of 1933 Weimar Republic had to face a choice between alt-right and alt-left. I hope we will never get into that mode.
