Re: The Aligorical Aliens!
I think people look too much into things. The Klingon Empire was by communist standards an imperialist society. Last I checked Kruschev and Brezhnev didn't fight to the death for leadership of the Soviet Union. The Romulan Star Empire was also a place where class mattered. The Cardassian Union was more a military dictatorship than a fascist regime as well. Just take the Trek races at face value... most of them aren't very deep... and leave it at that.
