The Southern Poverty Law Center is notoriously biased [1] against any non-progressive ideology, which includes alt-right and libertarian ideals. If this is indeed their actual opinion, it is wrong. I suspect even they know it is not true. Alt-right traces is lineage back to Ron Paul and the tea-party.

Do you have any sources to back up your claim the the term "Alt-right" can be traced back to Ron Paul and the tea party?

Wikipedia says the first usage of the term "alternative right" was by Paul Gottfried in 2008 (http://forward.com/news/national/348372/meet-the-jewish-pale...)

It also says that the first usage of the contracted form "alt-right" was by Richard Spencer. https://www.adl.org/education/resources/backgrounders/alt-ri... http://www.newyorker.com/news/benjamin-wallace-wells/is-the-... and https://www.nytimes.com/2016/11/21/us/alt-right-salutes-dona... quote Spencer as claiming to be the person who coined the term. And there's like a dozen other citations on https://en.wikipedia.org/wiki/Alt-right

Where are your sources?
