Communism in and of itself isn't bad, it's actually rather admirable. It just doesn't work. The reason it tends to become a dictatorship is because you have to MAKE people change their minds in order for it to happen. It's hardly a "threat", and some ideas aren't too bad. As you may recall, we do use some socialist concepts in our own government as well, we aren't pure capitalist by any stretch of the imagination. Look at our medicare and education systems. Of course, the government's doing such a piss-poor job of maintaining that, but still, they ARE socialized.
