in regarads to druids, shamans, users of white magic and grey magic are commonly associated with neopagnism as well, but so are nazis... but connecting the two, would be like saying a klansman and black panther both like burgers, so now they are related in some way... you just dont get it
in fact... if we dive into ritualistic origins... and older ages of tribalism there are believers of the same things that are completely and utterly ethnically different... there are correlating "origins" to voodoo, white magic, black magick, and what developed into a much bigger thing...
