Human beings are not herd creatures as the zany world of psychology likes to boost about. If humanity were to be herd creatures then war would not exist as we would all be thinking alike(think Holstein milk cows). Humans are HIGHLY SOCIAL by nature though, & the weaker folks in a society will turn to a groupie lifestyle in hopes that strength in number will get them through life safely. This is where groupthink(cult mentality) comes into play making these groupies ripe for the picking by elitist outfits like the U.N. wannabe gods. The statist left groupies(now sheep) see the U.N & think; "It's god we must worship it."
The ratio of leaders to followers in todays world is roughly 2 to 2-1/2 leaders to ten followers. With the statist left groupies literally frightened of everything including their own shadow, the U.N elitists must look like Big Daddy Jehovah on steroids to them!!! This is WHY I said above"...weaker folks in a society...", "(now sheep)" & unfortunately the frightened weaklings out number the leaders(individual thought capability) by about five or six to one. This has always been the case as far back to @ least the Akkadian empire. This is WHY the historical sociologists that study the past can so closely predict the future of humanity(human nature is a constant). With modern technology humanity can now exterminate humanity much more efficiently than Rudolf Hoess(pronounced Herse) & his Auschwitz/Birkenau creation ever could.
As you can see the "It's in your nature to destroy yourselves" statement is hardly a movie meme!
