"The Bernie Bros" is a phony narrative created by the Clinton propaganda machine....When I've run into people in forums and the like who fit this description, simple back and forth for a couple of minutes have revealed them to be either a.) Paid Hillbot shills or b.) Republican trolls (most likely a).
But the truth is i'ts deja vu all over again....The fictional Bernie Bros narrative of 2016 has its roots in the fictional Obama Boys narrative of 2008 (as does a lot of the Clinton dirty tricks currently being waged against Bernie Sanders, Gloria Steinem made ridiculous sexist comments about Obama too). The origin of the Bernie Bros defamation is the Blue Nation Review website owned and operated by David Brock. Brock started his career as a right wing character assassin writing a book attacking Anita Hill after she accused Clarence Thomas of sexual harassment then he had some kind of epiphany (perhaps involving something green with a lot of zeroes) and became a neo liberal character assassin attacking the victims of Bill Clinton sexual assault. He is the kind of amoral sleazy scum the Clintons associate with and nurture, the kind who would sell his own sister to the highest bidder, but the Clintons were born in the gutter, they live there.
