The prolonged Democratic primary is really causing the left to eat their own. Keli Goff of the Daily Beast has written a new column in which she accuses Bernie Sanders supporters of racism.

Take a look:

The Racist Side of Bernie Sanders Supporters

Black writers and activists who have had the temerity to challenge Sanders’s record have been targeted by his supporters in ways that go against not just civility but even decency. I should know. I’m one of them. For having the gall to share my perspective, buoyed by polling data, that self-described socialists are pretty much unelectable to the American presidency, his supporters attempted to harass me offline. (Emphasis on “attempted.”)

Let me explain what I mean by “harass.”

While thankfully, I have someone who works for me and wades through much of my mail and social media so I can spend as much time as possible writing (and maintaining my sanity and sense of humor), for more than a week Sanders supporters flooded my accounts with nonstop accusations—one more over the top than the next. I am “a disgrace,” “a liar,” a secret paid Hillary Clinton “mole” or “shill.” Apparently it is beyond the realm of possibility that I, as a free-thinking individual with access to polling data and a fairly vigorous intellect of my own may not consider their chosen candidate a strong one. Simply not possible. After all, as one white Sanders supporter informed me: “You need to be better informed on the needs of Black people.” Thanks for the tip!

But there were a couple of messages that made their way to me that were particularly troubling. One Sanders supporter pleaded on Facebook for others to stop attacking me and try to “inform me” (Again this denotes I couldn’t possibly be educated because I don’t agree with them, but at least he sounded civil). To which another replied, “She chooses to ignore the issues and work for her own personal interest. If that is the case than to me everything is allowed as long as it’s not physical violence.”

Consider that statement for a moment.
