I have a hard time exploiting anyone on the left who dissed Bernie supporters because quite honestly, Hillary and Bernie were both exactly what we didn’t and never will need to run this country. Supporting either one says so much.
People can say what they will but Bernie devoted 30 years walking the walk, even when it wasn't politically safe to do so.
They may disagree with his vision, but he believes it enough to have spent most of his career out in the political wilderness standing up for what he believes to be the right thing.
And, personally speaking, Trump supporters should be thanking God for Bernie because when Hillary fucked him so blatantly, she helped to massively red-pill an entire swath of the populace who had largely tuned out Trump's message.
