Setiosiris, I am quite offended by this accusation. I shall have to recuse myself temporarily from this thread so as to help regain my composure lest I say something unkind and impolite. I am quite distraught.
Sir, the very foundation of the world was built on tribalism. It is inherent to humans, we are, and perhaps shall always be tribal in one sense or another. We continually divide ourselves along lines of nationality, ethnicity, religion, tribe, politics, sexual orientation, and even video game tastes, and will do so for many generations to come.
