Paradox.
The pursuit of spirituality is a healthy and important aspect of humanity, allowing an individual to seek something greater than human understanding can encompass. It's metaphysical, and - being as it surpasses human understanding and all - unending. A first reaction to this statement might be - "So you advocate a lack of fulfillment?" But what I think most people don't realize is that they need something to seek. Subconsciously, answers don't offer any satisfaction, because the truth is seldom what you want it to be.
But as long as there is spirituality, there's always going to be the odd fuckass that thinks they've got it all figured out, nailed down all the answers and boxed them up in doctrine. And those fuckasses will convince dumbasses to start a religion, and a society of fucking dumbasses that everyone regards as a bunch of harmless loons will, over time, become a dangerous sect of radical douchebags out for blood and unity beneath their flag of idiocy.
So you know what, I say we just wipe out humanity. All of it. Bunch of knobs.
