Richard Spencer. I suspect anybody using the label that want ethno-states are either libertarians or regular conservatives and don't exactly need a separate term, meaning the only unique thing the term Alt Right describes are the ethno-state folk.

To add to this, you get a lot of ethno-state language in the weird world of some internet fringe groups: see shit like weebs and even bronies.

It's surreal as fuck but in my adventuring I've met more than a mere handful of bronies cheering on Donald Trump as the master of twelve-dimensional chess and actively seeking a world or a country without brown people. It's easy to draw them out too, just talk about Bookchin. And then there are those surreal as fuck [url=http://ironpiedmont1996.deviantart.com]Nazi apologists[/url] ("I'm not racist, I just recognize race exists", congratulations: you've learned people have different skin colors).

So in my opinion, when the topic of the Alt-Right comes up it is in the vein of Richard Spence as Vilage points out and these people.
