No such "original meaning" for alt-right exists, and I'll drive straight back to the wellspring if you make me. I study this stuff. The alt-right movement has, since its very inception, been the nexus of misogynistic and white-supremacist fearmongering with recruitment channels pulling from the chans, from games, and from the MRA community.

That is literally all it is and these attempts at revisionism are poor attempts at that.
