If you’re asking about the neopagan legend of “millions” of their spiritual forebears being killed by both Catholic & Protestants–the so-called “burning times”, this is just that–a legend.
The modern neopagan movement began in England in the 20th century, with a man named Gerald Gardner. Gardner & co. invented a lot of stories about how “oppressed” they had been. The only problem was that “they” had not been around (as a group/religion) to be oppressed (until the 1920s & 1930s).
This is not to say that there were no problems at all; like everybody, everywhere, all through history, the Middle Ages had its oddballs, villains, & heroes. They just weren’t practicing a so-called “old religion”.
Try reading up on Gardner, as well as Alex Sanders, GG’s rival in the world of “witchcraft”. They admit to inventing their “religion” out of whole cloth. Unfortunately, there are still people who believe their stories…But even most modern pagans will now admit to making up their own religions. The ones who don’t talk about “psychic revelations” & “channelings”.

OK, now I need

protection from :whacky: people who

dance naked by the light of the moon…

They can do that if they want to–& if they don’t freeze their #@*&**. Just don’t let them blacken the history of Christianity in the process!!
