Is Socialism a Buzzword?

CNN's John Sutter asks: Can you tell me the difference between a socialist, a fascist and a communist? The words all blend together. We have almost a problem with politics in this country where the same words are used by both sides or by every side because there's definitely more than two, but they all mean different things. This is just like buzz words that are thrown around of like socialism bad, communist bad. It's one of the biggest problems we're having right now.
