Yes name calling is alive and well on both sides. You are floored by this offensive albeit obscure insult. It is certainly rude. As a centrist, I however, am equally floored by the cavalier use of "alt-right" by the leftist media - a label attached to virtually anyone who questions the immigration system, the subversiveness of some "equal rights groups" (who fund riots and discourse directly, in order to gain funding) under the guise of equal rights for all, or someone who takes a sovereign/protectionist (you call nationalist) stance on other issues. Just look at Berkeley - many of you applaud the efforts of the students to riot, and destroy property with the goal of muzzling someone whose ideas conflict with theirs. The individual in question also happens to be a gay jew and immigrant. Do we call these individuals who chant "no borders no nations" and tag "kill trump" on the campus walls, the "alt-left"?
