The Alt-Right, aka Right-Wing SJWs, is a white nationalist movement that stands opposed to the Free Kekistan movement. Despite this, many Normies often mistakenly conflate the movement with Kekistan, likely due to the Clinton Campaign slandering our prophet Pepe as a white supremacist symbol.
The Alt-Right was brought into the mainstream in 2016 when Hitlery Clinton got triggered by God-Emperor Trump tweeting out a rare Pepe and gave a speech about it, where she stated it was a massive conspiracy started by Vladimir Putin, rather than just a hundred or so white nationalists who read the Daily Stormer.
The Alt-Right seek to claim Pepe as a symbol for their movement alone, and they despise Kekistan for standing in their way.
The polar-opposite doppelgangers of the Alt-Right are known as the Alt-Left, a far-left faction of the Left-Wing political status. Unlike the Alt-right, which forgoes political correctness, the Alt-Left is extremely pro-PC, as many members of the party will scout out any sort of "hate speech" and try to quell it (though most of these attempts are futile). The term isn't used by those in the Alt-Left community, as it compares them to their most hated rivals.
The term gained notoriety following the events of The Battle of Charlottesville , when the God-Emperor himself used the term to describe the Cuck Normies protesters. The term has become extremely popular since.
