I think in terms of communism Ants are probably perfect, the queen is not a ruler, her only purpose is to produce more ants. They are some what mindless creatures when you look at the individual but together they wage wars, farm, cultivate other animals, great builders etc... (emergance)
The best example I can think of democracy is google, if you click on a website it gets a "Vote" the more people who click on or "Vote" for a certain site, the more "power" the site has and it goes further up the list it goes. The further up the list it goes the more "Voteing Power" it has. This has been and still is being manipulated, of course.
Put it this way I would don't want to live in communism do you?
I could ask who are the educators and what kind of program they realize.
I know where you are coming from, I agree. I think it is importent to teach people how to think, not what to think, of course it is not easy to find, again the closest I can get to it is the scientific method.
any other animal in the animal kingdom that kills or harms other (whether same or different species) just to get his pathological rocks off, or out of hateful intolerance.
Ants have wars, dogs kill birds as presents, cats torture mice, apes have been known to kill each other, none of this happens out of hunger.
The reason Lions do not kill antelopes for the reasons you have stated is bescause they would stand to loose more, if the antelope were to injure the lion, the lion's chances for survival are greatly deminished. Same reason Nuclear Powers don't just go mad pressing that red button.
As for serial killers, I do not know enough about the animal kingdom but we are animals.
