What I'm pointing out is that all ideologies compete with others. That's the reality of the world. If Anarchists are not able to defend the way they want to organize society then their ideology ends up being trampled by others. That's the world we live in. Calling this victim blaming doesn't change the material reality of the world.
The difference between anarchists and communists is that the latter actually managed to build functional societies, and to effectively resist capitalism. Anarchists failed to do that, and the reasons for why anarchist approach fails time and again are well understood now.
What Bolsheviks achieved was the betrayal of all who fought for the liberation of the proletariat.
Repeating nonsense over and over will not make it true.
You speak as if the USSR only repressed the forces of reaction, but it also repressed the very same workers it claimed to support when they tried to claim the worker control of the means of production they were promised.
This is an idealist position that's divorced from realities of the world. USSR existed under siege from global capitalism throughout its whole existence, and that was the reason it was organized the way it was.
