Good point. After all, the opposite of democracy is not communism; it's authoritarianism (or fascism, or whatever you choose to call it). A democratic socialism is quite a comfortable ideology and exists in practice in many countries in different degrees. Sweden, for instance, is no less democratic than the U.S. simply because its tax rates are higher. Some would even claim the opposite. This is why the SE system of SMAC was a better idea. Damn Firaxis for going back.
