Clearly one of the biggest misconceptions people have about Trump's voters is that they're all these wacko racists, sexists, xenophobes, etc.
The truth of the matter is there's a lot of "normal" people who are supporting Trump, but not for the reasons you'd think. Their rationale is essentially "burn it all to the ground", which is why they'll be voting for Trump (or not vote at all), even if they know Hillary is more mentally stable and more aligned with their beliefs. They're so angered by what the Establishment's been doing for the past 40 years that they're willing to vote a crazy person in just to spite them.
If you think this sentiment is shared by the Bernie-or-Bust movement alone, it's not. Honestly, it's a sentiment that's shared by a lot of the global community. Here in Canada, I hear numerous claims on a weekly basis that America deserves Trump so that "they learn their lesson". In the UK it's the same. Some go as far as to include themselves in the statement, saying instead that "we all need to learn our lesson" since the US president is the main leader of the Western world and has major influence in the global economy.
Personally if I was an American citizen, would I really vote for Trump or give the election to him by not voting Hillary? I honestly don't know. My gut feeling tells me I'd vote for Jill Stein or stay home, but I might just drag my ass to vote for Hillary if I lived in a swing state (kicking and screaming, of course). I don't know what the right call would be, but there's one thing that I do know and can't stand about the Hillary voters. That is this idea that if Trump wins the election, those who didn't vote for Hillary are the ones at fault for it.
No...just no. To quote Chris Hedges, "fascist movements build their base not from the politically active but the politically inactive, the 'losers' who feel, often correctly, they have no voice or role to play in the political establishment." You can't actively disenfranchise your population and still expect it to act rationally. All you've done is put them in a place where they feel helpless, which will only lead to them being desperate.
So if Trump wins the presidency, that is the direct fault of the Establishment (and more particularly of the Democratic Party). I don't see how Bernie's camp or anyone else's camp can be demonized for it more than the Establishment should.
