I've never seen anybody advocate for recreating USSR the way it existed. What people actually say is that USSR managed to accomplish a lot of positive things despite the problems it had, and there are a lot of valuable lessons that can be learned from it both positive and negative.

It's also absurd that people keep fear mongering about existing Communist projects because each one of them is rooted in history, culture, and material conditions that it arose of. It's pretty obvious that if socialism ever came to the west then it would have its own unique characteristics based on western culture and values. These are idiotic arguments designed to shut down discussion and scare people away from even thinking about communism as an alternative to the capitalist hellscape they live under.
