SHORT VERSION: Being alt-right today means you want an America that’s all white and you hate Jews. We have plenty of non-white members and we also have a Proud Boys Israel chapter. So, you got the wrong guys.
LONG VERSION: Journalists are about the only people left who don’t know what “alt right” means. Sure, it SOUNDS like it means “a right wing person who seems kind of alternative” and it may have meant that when Richard Spencer started it ten years ago but times have changed (and so has Spencer for that matter). Today, it has drifted so far right, it now means a racist anti-Semite who blames Jews for the world’s problems and wants all other races out to get the hell away from white America. If the Proud Boys must be on the spectrum they most would classify themselves as libertarians or New Right AKA “alt-light” (the latter being a derogatory term the alt-right made up for us but we kinda like it).
The alt-right also appears to advocate for socialism and atheism and other strange traits of the far left. In fact, you could say the political spectrum is no longer a rectangle, it’s a circle where alt-left and alt-right are touching. Both hate Israel. Both abhor Christianity. Both are obsessed with identity politics (alt-left hates whites, alt-right hates non-whites). Here’s a chart in case you’re not already confused enough.
