Milton was a staunch Christian. It was interpretations of Paradise Lost a hundred years or so after it was written by the likes of William Blake, Mary Wollstonecraft, Lord Byron and Shelley that were the formation of Romantic Satanism, which in turn inspired the modern atheistic, compassionate Satanism of today.
Fair warning: some of it is very disturbing. There's a lot of quoted racism, antisemitism etc. It's not an easy watch. If you make it through the whole thing, there's also some very interesting comments left by current and ex members too.
Thank you for linking me that video. Just finished it and wow. Disgusted but overall happy to know all that shit and part ways with them. Fuck racists, transphobes, eugenics, fascism and the capitalist underpinnings of TST. *spit
I wish there was a way but there's so much bad stuff and it all kind of interweaves with every other aspect of itself. I could tell you Greaves was a eugenicist who's made eugenicist, racist, antisemitic, ablist statements in the past but without going through everything else in the video its next to impossible to explain how that impacts on how he operates today.
Neither of them are good people but I don't want anyone to just take my word for it - the receipts are at that link.
The video has its sources listed in a Google Doc in the description, but if reading rather than video is more your thing (or you're not keen on using Google stuff - and I get that) there's also TempleWatcher's pages on Greaves and Jarry, the two co-owners of TST.
I don't know the specifics and everything I have heard has been third or fourth hand accounts, but apparently the recent drama has been bad and has caused a real upheaval.
My local TST group voted to separate from TST and become independent, so now we are working on becoming our own local group. But it takes time to do all the paperwork and stuff.
