Immaturity is the special hallmark feature of humanity. Immaturity is what makes us, defines us, drives us, affects us, guides us, supports us and destruys us. Every single war, murder and other crime in the history of mankind has, once you get to the core of it, been driven by immaturity. The current "War on Terror" should be included in the definition of immature. Racism and other kinds of xenophobia are at the very root of immaturity, together with all this material gain stuff that keeps humanity from reaching full potential. And there's more: Hedonism. This keeps us generally from satisfactorily completing any single thing. Bureacracy is a pseudonym for immaturity. Fascism, oppression, exploitation, spam (Both mail and posts), violence, bias and, of course, childishness are all incarnations of immaturity. Immaturity has for centuries been the main foe of the great people of science, religion, philosophy, poetry, literature and society in general. None of them ever managed to remove a single sub-quark particle of it. Indeed, their works have usually been turned around and used to promote it. Case in point: Marx, Muhammed, Jesus, Nietzsche, Norse mythology, Greco-Roman mythology...
You think all the people out there, who cling to their immaturity as right, noble and self-evident, will just suddenly see the light and mature overnight? If you can pull that one off, I'll wordhip you for eternity and be your humble slave. But somehow I doubt it.
