The Unarians have nothing to do with Scientology.
Yes, they are a UFO cult, with smatterings of ancient Egypt and archangels. Their founders were a pair of uh, creative thinkers. Ruth Norman survived her husband and her vids are still played on public access tv. She favored elaborate wigs and costumes. Their temple has books for sale, a working Tesla coil, and an interesting model of their vision of the future ideal city.
Many of them are quite elderly. Ruth passed away in 1993, but the organization continues. They are a benign group, and there is no reason to enturbulate them.
Shydavid (Desertphile) and I visited their open house a few years ago. The people were friendly and not at all pushy or rapacious. Go visit them if you're curious, but be polite and respectful, as they don't bother anyone. You won't need masks. They're not Scientology.
