The so called Communism of which you speak is/was actually totalitarianism, covered with a thin veneer of "Communism".
True communism--where everyone works for the community; where work and resources are equally shared, based on need and ability; where no one is in charge--would be a good thing.
It's been over 160 years since communism was suggested. All countries that claimed to be communist or headed that way were totalitarian. At this point I think it's safe to conclude that communism is de facto totalitarianism.
