They are trolls that the democrats PAID to create the vast alt right conspiracy. The alt right "scum" are just hard working democrats creating a new reality.
So Breitbart is employing Democrats now? Trump is retweeting and following Democrats?
Most of the #AltRight wouldn't be considered GOP even by themselves, but if it's a DNC Conspiracy it's a very long lived one and a very deep one. The #AltRight accounts on Twitter aren't made up fly by night accounts. They've been there for a while, host podcasts, have websites, hock merchandise for their cause, etc. If the Democrats can create a hoax of that level, then you may as well give up because they've attained God level reality warping status.
