As we all know by now, two members of Black Lives Matter recently prevented Bernie Sanders from speaking at a rally in Seattle in support of Social Security and Medicare. A number of Facebook friends of mine have tried to defend what they with the following argument: they forced Sanders to take more substantive positions on race issues. I can’t agree with this argument for two reasons. First, this tactic has clearly alienated many people who would otherwise be sympathetic towards Black Lives Matter. Was it really worth doing that just to get Sanders to take slightly better positions? Second, if you say that Sanders takes good positions just because two people forced him off the stage, that makes him look weak, doesn’t it? What good does that do?
