Nobody really has any interest in African religions. There are tribal wudu religions in Africa which seem like an ancient continuation of Odinism. They aren't perceived as an archetype of ancient wisdom like Native American and Asian religions are. Some may say these religions are just shamanism and tribal memory; it's just proto-codified mythological history and has nothing to offer Westerners the same way that something like the Greco-Roman mysteries or Egyptian beliefs do. Maybe it really is racism behind it.
