I don't see why that should concern us. It was annoying to be blamed for 2016 because there was nominally an electoral left that was trying to win over "progressive" liberals. Getting tarred for spoiling the agenda of the party was counterproductive to the goal of improving the agenda of the party. Now that that strategy has failed utterly (largely because the non-voting population could not be convinced that that shit actually mattered) and the champions of the electoral left are riding the Sybian for AIPAC, it doesn't really matter that we're the enemies of the Most Progressive US President in History. Damn right we are. The whole thing's a farce, and we only neutralize all hope of resistance by pretending otherwise.
