The mass incarceration, demonization, and assassination of leftist figures by apparati of the state at the behest of the capitalist class?

that's table stakes. it comes with the turf. every communist movement starts out facing these problems. stalin famously had a printing press in a tunnel under a well in a backyard in tblisi, until the tzar figured it out, dynamited the printing room, and burned down the house. the first task of any serious revolutionary movement is to competently manage these risks. also, it helps not to self-sabotage like many of the current movements.
