Since the left is so obsessed with race, let's take it in from their perspective.
From what I read, There were multiple videos of how the encounter escalated. it was over a black guy's T-shirt that said "Black Guns Matter". Of course, the white knight in the equation accused him of being a Trump supporter, but he wasn't. Yet, the valiant white knight wouldn't drop it, the people rallied against the black dude, and it escalated.
Amazing how people are so static.. as if someone who believes in the 2nd amendment couldn't possibly be a follower of Bernie Sanders.
Meanwhile, the media predictably initially reported him as a Trump supporter with absolutely no context or knowledge of the situation.
I mean... how many examples of media malpractice that always err on the side of the left do you need... it happens 10 times a day.
