trying to define Alt-Right?

The alt-right is a somewhat amorphous label for a what Southern Poverty Law Center defines as “a set of far-right ideologies, groups and individuals” whose core beliefs rest in the notion that “white identity” is under attack by “political correctness” and “social justice.” These forces are acting to “undermine white people and ‘their’ civilization,” according to the law center.
American Renaissance defines the alt-right as a “broad dissident movement” that rejects the principle that all people are equal. Race is central to its philosophy. Here’s American Renaissance in its own words:

The movement, called different things as it festered on the margins of politics for decades, appears to be gaining a boost during this presidential campaign. Google Trends shows interest in the search term “alt right” as very low from 2004 until about April 2015. Since then, searches for the term have quadrupled.

The 'Alt-Right' Is Thrilled By Hillary Clinton's Denunciation

I'm thinking that the Alt-Right movement is a reaction and the blow back from Black rights, Brown rights, Yellow Rights and Red Rights and Women's rights. It is a realization of the death of the Republican parties ability to elect another President because of demographics. It is the horror of white people realizing they are going to have to share power with all the other races on earth. And the lack of birth control means white people who actually use birth control more are being bred into a minority.

Then you add the fact that when a white person breeds with any other race the first attributes lost are white skin, blonde or red hair and green or blue or hazel or lavender eyes and sometimes light brown hair.

So, white people who live in the middle of the U.S. often have never met or made friends with someone of another race and are socially unprepared for this outcome at present. Whereas people who live on the coasts of the U.S. or borders of the U.S. (North or South) are most used to dealing with other races and peoples from all countries on earth. So, people who are alt-right tend to be middle Americans for the most part or from the south.
