Lefties have tried to change the meaning of far right to mean nazi poopyhead. Of course they are oblivious to how outside of the nationalistic slant, nazism is a lot more similar to their views than they realize, especially these days when they are acting like totalitarianism.
If we consider communism the farthest left, and libertarians are the most opposite of communists (minimal power for government), then libertarians would be farthest right.
There's somewhat of a horseshoe effect when it comes to anarcho-communists and anarcho-capitalists. A true propopent of each would believe in things like open borders and have a hatred of "western culture". As a matter of fact the boogeyman to the left and conservative Koch brothers are who spent a ton of money pushing open borders propaganda as it helps large businesses drive down wages. People on The Donald typically love their fellow countrymen and traditions too much and understand how detrimental open borders would be to the working class. I think a lot of users here would be a paleolibertarian or paleoconservative. Trump sits somewhere at the intersection of those and nationalist and populist.
