I think it would be best to start a new religion, one that both Christian and nonChristian can belong to. Sort of like how both Christians and Japanese Shintos can also be members of certain forms of Budhism.

A religion has a very practical aspect. People need ceremonies like weddings, and a religion gets legal protection.

I am thinking in line something similar to the World Church of the Creator, but more inclusive. It would have to be somewhat vague so not to violate the principals of Christianity and other belief systems.

Beliefs would include Rahowa and that the Jews are Edomites, the hated of god. It would be a secular religion that all whites are welcome to join.
