People on /pol/ quite often post views which are actually leftist, but they hate brown people so much that they can’t bring themselves to abandon the far-right.
There’s nothing to abandon the alt right for. If the democrats decided to run on a platform that was even remotely progressive, do literally anything for worker’s rights, they’d win a lot of disenfranchised voters. Obama won, and that’s not because all of a sudden, just for a moment, America wasn’t racist. No, it was because he promised to solve one of the problems that’s killing Americans in every stratum: healthcare. Instead, we get fracker and border wall builder Harris.
