Dogma
Most secular and progressive people are inherently resistant to any established belief system due to the fact that once you establish one it becomes dogma. And once you have dogma you have hierarchy, resistance to change, and the truth leaves you behind. This is understandable, but it puts them at quite a disadvantage when it comes to appealing to those who are seeking out a belief system and don't really want to have to figure everything out for themselves.
metaculture avoids this issue by making science and the scientific method at the core of that dogma. This means that the only dogma is that there is no dogma. That is something that progressives can believe in and say that they stand for, because it will always be true.
Of course, beyond this base assumption is all of the knowledge and evidence that science and religions have gathered over the course of human history that must be taken into account when developing a belief system, documenting best practices, and making life choices. metaculture creates a malleable, self-correcting dogma that makes recommendations based on the best of our current knowledge, and stays up-to-date when new shit has come to light.
