Our general repression of matters disgusting prevents us facing up to a serious health problem. If we are the 'god that shits,' then we are in full flight from ourselves. I even wonder whether religion itself and the whole idea of a god is produced by our self-disgust.
I became a vegetarian out of compassion for animals and to live as healthy as possible. I realized soon after that I was truly concerned with nonviolent consumption and my own health, a vegan diet was the best decision.
