The number of Sanders supporters who didn’t vote for Clinton is small, certainly compared to the fall in turnout between 2012 and 2016.
Regarding the anti-SJW ‘bros’ on the left: as others have said they are numerous, and their belief stems from the idea that issues of class override all other concerns (to the exclusion of intersectionality), that ‘tinkering’ around the edges of neo-liberalism on issues such as language etc is a distraction, and also that the state and corporate america are one and the same. I can see where they are coming from, although I can’t agree with that, and would have thought that they’d have read Chomsky enough to understand why it’s not a zero-sum game.
