Communism is but one form. One political system. One that fails time and time again. The evil people you are referring to may or may not be communists but they do seek power over anything else. I suspect there are plenty of socialists which isn't any better.
The system that has been constructed is far worse than communism because it is not completely centrally controlled. I believe we are much closer to fascism than communism. Communism lacks any free markets. No privately held companies. Fascism was not defeated in WW2. It spread to the US and many democracies.
Power corrupts. Its all about power. All these systems end up being controlled by sociopaths. But they need the people to go along. Don't do it.
Declare independence. American ideals are not politics. Its about freedom, liberty, and hard work. Enjoying the fruits of your labor. Finding the value in others.
