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 Bolsheviks' had the ill-gotten might to push their agenda, but might does not make right. The Bolsheviks lied to and used the anarchists to achieve what they did, but anarchists have learned from their past mistakes and will prove you wrong.
USSR existed under siege from global capitalism throughout its whole existence, and that was the reason it was organized the way it was.
Capitalist aggression did not make necessary the regressive views on social issues and science the USSR had (which resulted in famine), nor the widespread corruption and bureaucratic inefficiency of state officials. You cannot simply excuse all flaws of the USSR by blaming global capitalism.
