People say that I only think that Farblesnozz is the one true God.

nietzsche had his idea of a post-religionist world where mankind would itself be deemed the highest good. but that implies that the world religions never served that purpose in their past. they did serve that purpose in the past and are now existing mainly to serve themselves, i.e. not mankind. small communities of consensus and "storge' (a greek word) might be one way to develop these ideas further.
