[@Dynamo Frokane] I think that's a bit of a No True Scotsman fallacy. There is a substantive difference between white nationalists and alt-righters. 
Qualitatively the alt-right is high energy while white nationalism is focused energy. The alt-right is an emerging portion of the cultural zeitgeist while white nationalism is the latest head of an ancient hydra. 
Qualitatively the policies they endorse and the members they attract are quite different. Many of the highest profile alt-righters are minorities of some sort. Jews feature prominently; Milo and Ben Shapiro are extremely popular and being a minority who endorses Trump in a big way will make you a celebrity within their circles (see Joy Villa).
In the white nationalist movement it isn't that way. While it isn't purely white men, there are some white women, it is almost entirely populated by white males.

Also, the alt-right is not a libertarian movement. Trump's election was the death of libertarianism as a political force in the USA. His policies are strongly anti-libertarian and he didn't even bother to pay lip service to the economic fundamentals of libertarianism. Conservative voters are clearly not moved by libertarian economic principles any longer.

[quote]I would be more interested to how you feel about the alt-right in regards to their Ethno-nationalism, Race Realism and Anti-semitism (they vary on these topics, but they usually agree with 2 if not all 3).[/quote]

Man. Dangerous question lol. Hrm. Alright, I think white nationalism is a lot like communism. It's linked to failed regimes that are extremely unpopular and is largely a spent force outside of eastern Europe and Russia. I would say these elements pose a serious danger to the alt-right though; as one of Trump's kids might say they are poisoned skittles and you probably wouldn't eat any skittles out of the alt-right skittle bowl if one out of every one hundred was a racist white nationalist skittle. 

That said, times are clearly changing. White nationalism has a chance to make a comeback (just like communism) because of broad shifts in society. As society becomes more diverse white voters will vote more and more like minorities and as they become a minority they will develop a racial consciousness as well. Racism is no longer the social kiss of death that it once was. Some ideas out of white nationalism will become mainstream due to demographic shifts just as some ideas out of communism will become mainstream due to automation (basic income, for example.

I think within the next fifty years you will see a republican party that wins 90 to 95 percent of the white vote in every election. Basic universal income will be a popular policy with both parties. Free market conservatism will be a complete non-starter with both parties. National elections will probably come down to mobilization along racial lines but the cycle of one two term democratic president and one two term republican president will probably continue. This might sound like good news for the communists and the white nationalists but I think both sides are going to be miserable when they get a little of what they think they want. What we could have had was better but we don't deserve it so we won't get it.
