Alt-right is a term devoid of meaning, it has been abused so badly and so often. No one can agree on what it means, so it cannot be parsed as anything more than "those people I don't like, who entertain bad thoughts."
Alt-right is basically a fancy label for 'outside of the mainstream, doesn't like political correctness and isn't in favour of Clinton' by this point.
It's basically used like the 'Bernie Bros' thing was when he was still running for president. A near meaningless buzzword to insult people the user disagreed with.
There is no “alt-right”; they’re just the far right. “Alt-right” was just cool new branding for the same ethnonationalist crap that’s always been around.
Alt right is a political term coined by a white supremacist, and encapsulates reactionary ideologies and intolerant, hateful and violent attitudes towards certain races, faiths and nationalities. Those who identify with the term or act accordingly can be accurately grouped with their ethos of violence, and have their ethics and politics more accurately summed than entire nationalities and/or world religions can.
FWIW, there is no single definition for "alt-right". You're free to choose the definition that best advances your political leanings, but implying specificity to one description seems a bit disingenuous to me.
Literal Nazis are German White Nationalist Socialists. That's not what the alt-right is. The alt-right is a blanket term used to describe anyone right of Bill Clinton who is currently not a media darling.
Fascists or Ethno-Centrists are both better terms, and cover the ideologies that most people attribute to the alt right.
