There’s much to learn from Stalin. But, advocating his authoritarian means is a bannable offense there just as they are in any meritable leftist forum. They tolerate a minority of revolutionaries ideologically leading the lumpen as it’s a historically very well-supoorted position. But, that doesn’t extend to physical force as that’s also a historically very well supported position.
It’s much easier, convenient, and comfortable to demonized them than understand them. They even provided proactive assistance when many were deciding if they should defederate. They voted internally for defederation to defend their community from the medicrity of the masses.
