Richard Spencer And The Alt-Right: Neo-Nazis

So I've been wondering what the hell the alt-right is.
I've been unwilling to buy the line that they're a bunch of neo-Nazis because, well, that's the line that the left has taken up...and you know how crazy they are now. Everybody who disagrees with them by an iota is a racist misogynistic x-phobic retrograde fascist. Them being frothily against something is damn near sufficient for me to think it might be ok...
But this, especially the video...well...equivocal it ain't.
It's kinda nice to have a question that can be answered unequivocally, astonishingly repulsive though the answer might be. I mean...'hail Trump'? Actual Nazi salutes? Where does one find a whole roomful of such unmitigated fuckwits?
