6th-Density Negatively Polarized Wanderers?

[turtledude23]

I'm sure negative wanderers mask as positive figures, so I imagine Ra didn't want to cause confusion.

I think the reason Ra with held that information was because a large portion of the wanderers on Earth now are likely formerly of the negative path, meaning the person who's reading that could be one or someone they know could be. If you knew someone on Earth right now who used to be 5D negative your perception of them would change regardless of how mature your beliefs about STS are.
