In my Linguistics class we were talking about the Tower of Babel... and I know we all realize that god is a dick, but I never really payed attention to this one before.
So it basically goes like this: all of humanity (god's creations) are working together to build a tower to heaven so that they can meet their father and almighty god. Well god, he doesn't like this at all. 'How dare they try and attain perfect happiness through cooperation!' and he makes everyone speak different languages so that all the esprit de corps is completely in vain. So since god was upset at our camaraderie, he made us forever live in discord.
The moral of the story? Peace and love are for chumps. Differences matter.
(god's an asshole)
