Satanic clubs, whose members do not worship the devil, usually formed in response to presence of religious groups in schools
Community members in a Tennessee school district want to banish Satan from their children’s halls after the formation of a new club was announced.
The After School Satan Club (ASSC) wants to establish a branch in Chimneyrock elementary school in the Memphis-Shelby county schools (MSCS) district.
The ASSC is a federally recognized nonprofit organization and national after-school program with local chapters across the US. The club is associated with the Satanic Temple, though it claims it is secular and “promotes self-directed education by supporting the intellectual and creative interests of students”.
The Satanic Temple makes it clear its members do not actually worship the devil or believe in the existence of Satan or the supernatural. Instead Satan is used as a symbol of free will, humanism and anti-authoritarianism.
The Satanic branding is basically the trolling and meant to be provocative, at least that's what they say on their About Us page. That's one reason other (more insane) Satanists hate the ST, because they basically openly admit to appropriating Satanic and pagan imagery in jest which is sacrilegious to "real" Satanists and some pagans who actually believe the symbols have power. It works in the sense the ST is a political advocacy group though because it freaks some Christians out.
