There is actually something worse than a fascist, and that is a coward. MLK Jr spoke along similar lines when he said that the biggest enemy of black liberation is not the racists, but the white liberal coward. The biggest enemy of the USSR was not Adolf Hitler, but the revisionist movement that would lead to decades of corruption and its eventual demise. The biggest enemy of the western left is not Donald Trump and his ilk, but the petty, weedling cowardice of so-called comrades.
If you are unable to even attempt to unify, and you are unable to even take an opportunity to benefit the movement with your action when the opportunity is placed right before you, and you flee at the first sign of conflict — and yet still call yourself a socialist — you are worse than the dipshit I just blocked for parroting neo-Nazi rhetoric. You are worse than any multi-billionaire, any neo-McCarthyist. And as far as I'm concerned, you are welcome only to leave.
