The bible. PHHBBLlllpptt. I'd sooner use the Anarchists Cookbook as a guide to how to lead my life. People who say they follow the guidelines of the bible are liars, because nobody could follow all the commands in the bible and still exist, it's impossible. We're not saints or angels and we were never meant to be.
We're the rough smut of beasts, as Walt Whitman put it. We're human animals and we shouldn't pretend to anything more, we need to start helping each other and realizing we're in this mess together and no fictional supernatural being is going to come to our rescue or provide us any sort of comfort.
