The reason why some find it unacceptable is because they aren't exposed enough to Bernie's message, so they're walking around thinking he's some extreme radical lefty loony communist. The media tells them one version of his policies, not a very flattering one, and that's the narrative they know, so when you meet one and ask them about Bernie's universal healthcare plans, they immediately ask 'well how is he going to pay for it?', essentially parroting CNN pundits, as if the military budget doesn't get a multi-million dollar increases every single year, despite the fact America already spends more on military than the next TEN (!!!) countries combined and nobody ever asks how they can afford that.
They've managed to convince voters that somehow any socialist programme or policy is going to be so impossibly expensive that it'll eventually tank the economy and they'll end up losing their jobs.
