there exists many "satanists" out there, that those "media" would most likely not even concider being a "satanist" ... since they dont fit "common description".
I literally put satanist down on my last federal census, and follow the tenets of the Satanic Temple, but I doubt that most people, let alone commercial media companies, would identify me as a satanist, because most people have a lot of assumptions wrapped up in that label.
Meanwhile, I volunteered at a christian-run charity shop for years and only had one single person do a double-take at my definitely not christian religious jewelry.
