Over on another site, I instinctively defended the premise that the Black Lives Matter protesters were foolish, at best, for protesting at Bernie Sanders events. No real need to recap the arguments here, but I've since read some convincing explanations for why BLM should, in fact, target progressive events where they want to emphasize the importance of their message in the line-up of priorities being discussed. Heck, while I immediately took the "don't shout him down, free speech doesn't work that way," stance, Sanders went back to the drawing board on his own policies and priorities.
