The slippery slope really does exist but it isn't what people think it is. What if we judged people not on how rich or poor they were, but rather on the philosophy they keep? What if we were able to choose teachers for our children, our co-workers, or who we count as friends, based on the soundness of their philosophy? Better yet, what if we chose our politicians based on the soundness of their philosophy?
