That's a good post, fizzy. But at one point you say Communists want "to belong to a 'commune'" (more accurately, I think, is to say that they want their SUBJECTS to belong to a 'commune'). That doesn't apply very well to Reagan, Attila the Hun, and some of the others you listed.
You're lumping Fascists in with Communists. While there is a lot of common ground between the two, I think FASCIST is probably the better, more accurate word if you want to encapsulate ALL of the Morlocks and Eloi.
A Communist (Obama, Clinton, Clo, Stalin, Kennedy) is almost always a Fascist. But a Fascist (Reagan) does not have to be a Communist.
