That was quite the rabbit hole, I had no idea a global cabal of neonazi "Satanists" was spawned in Shropshire back in the late 1960s. I poked around Amazon and you can still currently purchase their books, which look completely ridiculous but have mostly positive reviews.
A metric fuckton of weird magical societies were created in the UK in the 60s/70s. It was kind of the hotbed of modern occultism.
For the O9A i had no idea they were neonazis, but they've always been considered edgy teenage satanists by the community. To be fair i thought they had died down a couple decades ago.
