Since I'm Satan and all, I think it's my duty to explain what Satanism is. First of all, yes, it is an actual religion. Actually, it is more like an ideology or philosophy. However, it is divided into two branches: dark satanism and light (LaVeyan) satanism. Dark satanism implies retarded children in dark coats with devilish horns and make-up, who sacrifice poor animals in dark forests while preaching Satan, a red-skinned muscled sexy demon with bull's tail on it's back (at least that's how they imagine him). This movement formed the most well-known stereotypes about satanists, despite that the dark satanists do not have proper ideology and ideas. Most of it followers are just fanatics who read the books of unknown authors and as a result, they slightly went nuts. The light (LaVeyan) satanism, however, is more interesting. It was founded in the 1966 by an American philosopher and occultist Anton LaVey. It movement is divided into two branches: right and left. The right light satanists are anti-religious: they do researches on the Bible, rant against the Christiniaty by bringing quotes from the Bible and accuse Pope Francis and his friends in crimes and corruption. The left light satanists have an ideology and even their own Satanic Bible, a book which is divided into the book of Satan, book of Leviathan, book of Lucifer and book of Belial. Two of these books are dedicated to describing rituals. One of the books describes LaVey's hate to the church, here he leaves quotes from the Bible and criticizes Christians. Other book explains the philosophy of satanism. What is really interesting about the left light satanists is that they believe that you are Satan. We are all Satans. And we all should live a life without any barriers as there is no Heaven nor Hell. We created God for ourselves and this is why human is the centre of the universe, not some old guy on the cloud. The individual should choose his fate himself and do what he considers correct. Basically, the whole philosophy is the form of light egoism; human should do what will satisfy his own demands and make him better in the frames of adequate. Regardless all the serious philosophy ideas here, LaVeyan Satanic Church members are retarded silly clowns as well. All of the so called "rituals" are sucked out of the finger: there is no idea behind them or even if there is, it is very complicated. Well, that's a lot of writing.
