Go ahead, so long as it dosen't have any of that dicatorship of proletariate shit in it. That bit of ideology trapped the Russians in a very long, very cruel dictatorship.
It's dictatorship of the proletariat in contrast to what we have now: the dictatorship of the capitalists. It means the working class is in charge. It's not about dictatorship in the sense you mean. But few marxists would use this terminology anymore because it's too often misunderstood.
Certainly some things went badly wrong in the Soviet Union, but not because marxists were talking about "the dictatorship of the proletariat". In fact, many problems stemmed from the fact that they didn't have a true dictatorship of the proletariat.
