The compulsion that you feel to distance yourself from past proletarian movements so that your attackers won't associate you with the supposed atrocities of those movements only functions to move you further and further right. It doesn't work because the attackers will do it regardless of how much you moderate yourself. This instinct leads you to not only distance yourself from their own goals, and to condemn your own movement, but to uphold reactionary lies about our movements, sometimes even outdoing those lies by exaggerating them, in order to further emphasize the attempt to distance. It doesn't matter how much we try to twist and turn and distance ourselves from atrocity propaganda, rubbish will be heaped upon the graves of working class leaders.

Functionally all this compulsion does is move you rightwards. You are attempting to make yourself more appealing to the right because you think that doing so will magically make people on the right suddenly like socialist politics. In the meantime they will attack you with every single piece of propaganda regardless, and you will moderate yourself even more. This deradicalises the movement and blunts the radical edge it requires to get things done.

It's exactly the same compulsion that liberals have that has caused them to move further and further right over the decades. Every time they get called a communist by the republicans they desperately try to move rightwards in order to get it to stop happening, it will never stop happening though because it is not said in good faith, and the tactic of accusing them of it works well in moving them right.
