A commenter on the facebook version of the "label, schmabel" post pointed out that the list seemed a bit complex, and said that for her the bottom line was whether the belief system was oppressive or empowering for women and lesbians.
That is part of the bottom line, for me. For instance, I don't see how women can be empowered without liberating men from the oppressive structures of patriarchy too. Another friend lives by Socrates' question, "How shall we live a good life?" which also seems like a good test. The spiritual is political, as many people have pointed out.
I guess my "bottom line" or Occam's Razor would be "Does it contribute to the well-being of all beings?" (including women, men, LGBT, queer, animal, tree, discarnate entity, Gaia, etc.) But one still needs to unpack exactly what that means and how it works out in practice, hence my previous complex list. But I can see how the list would seem weird if you didn't know what my bottom line was.
