"Alt-right" is a successful Alinsky tactic employed by the left. Specifically, it is a term coined by Richard Spencer to define his group which is an alternative to conservatism. Richard Spencer is a vile human-being who only has a platform because he has been empowered by the left. The left has empowered Richard Spencer because he represents what the left wants the right to be. He is their strawman. The left then uses "alt-right" as a vague umbrella term to describe classical liberals, libertarians, conservatives, those who oppose political correctness on college campuses, those who criticize modern feminism, those who dare utter the phrase "cultural marxism", and anybody else who criticizes or opposes the modern left. Once you are able to label someone or something "alt-right" you no longer have to develop a counter argument or even think. The term serves its purpose as it is able to conflate those who reject group-think with evil, vile human beings. This label grants moral high-ground to those who use it, thus allowing them to dismiss opponents rather than debate them.
