I said keep because it's a line from a movie. Chill out. But seriously apologizing for an opinion has nothing to do with communism.

Underlying idea bud, not direct translation.

Lack of freedom and whatnot is not even an underlying idea. The reason that it is associated with it is because the only way communism is ever implemented is with a dictatorship, which takes away freedom. If people would accept communism freely (which far more than a majority don't and never will, which is understandable), then a true communist society could exist, freedom and all. So the word you were looking for is dictatorship.
