I mean, they are traitors to the cause, but other than how hilarious it is to call them out as indistinguishable from right-wing bootlickers except for their team colors... at some point, we do have to accept that there are fucking lunatics who are in broad alignment with our goals. Such is unavoidable in any ideology.

MLs do, nominally, want communism. In the same way that both mercantilists and alchemists want gold - only one has a realistic conception of how to get there, while the other is busy chanting magic formulae and blindly following superstitious cults, but they are both definitely gold bugs.

In that sense, I don't begrudge them the shared usage of the word 'Communist', especially considering the widespread usage during the SovUnion's existence - so long as we can emphasize that their red-painted fascist lunacy is not the only 'Communism'.
