my 2 cents: he's right that bernie sanders doesnt correctly address race issues, but it's because bernie is a soc dem who (whether willingly or mistakenly it doesnt really matter) misunderstands and misrepresents class struggle, and that to actually combat capitalism ignoring/downplaying the racial aspect of classes in capitalism is to totally misrepresent reality and thus have no chance of actually achieving real meaningful progress towards socialism.
even though he does mention that this vid was specifically directed toward electoralists, he still took a shot at revolutionary socialists anyways so alongside him totally ignoring bernie sanders other glaring issues (laptog for imperialism etc.) which arise from the same place as his lack of attention to black issues, i think this was among FD Signifier's bad videos
