or know a bit about their history... from the 1960's onward (as I remember)... there was a rift brewing back then among the congregants. LaVey was very authoritarian, very ceremonial, very Darwinian in his view of society. His view would not be favorable among most of us here, and among many in his Church of Satan who joined for the rebellion factor as well as other factors, it didn't sist well, either.
Eventually, they schismed into the Satanic Temple. The Satanic Temple's views and beliefs very closely align with most of us here. Satan is not really even a philosophical construct for them; they truly are based more around a humanist set of beliefs. But they kept the "Satanic" to trace back the lineage from which they came. This isn't unusual among pagan groups that hive off other groups, for whatever the reason.
I remember one other group that arose around this time that, I think, should have carried more appropriately the moniker of "Satanic" in both name and rituals. No idea if they're still around, tho... they were called The Temple of Set. Perhaps they've stayed completely out of politics and concentrated completely on religion and rituals, instead, if they're still around.
Some of these groups arose around the same time as the Church of Eris arose (Hail, Eris!) and the Church of All Worlds (CAW). This was the heyday of PodsNet during the old BBS days. Disclaimer: I ran FidoNet and Podset (among others) on my BBS, Tapestry, out of Kansas City, Ks for decades. And loved every minute of it!!!!
