A misunderstood term. There are many different faiths under satanism the most common is LeVayan Satanism, founded by Anton LeVay. It is attached to the Church of Satan and the Satanic bible. It is a more atheist (as they prefer to call themselves) point of view. Practicing rituals and spell writing and incantation relates it to Wicca or Pagan groups. Though the group practices magic, majic, magick, majik, or how ever you would like to spell it they do not believe in a celestial being or "God" except for themselves creating the philosophy "You are your own God" a point of view meaning you choose your own destiny not a false being claimed to have created all the existence from nothingness. Another View of satanism believes Satan was the true creator and during an inquisition the catholic church stole satanism and turned it into the opposing religion. These satanists usually practice the Ars Goetia, or the art of summoning of the 72 demons. They practice summonings, rituals, and spells found in LeVayan Satanism. Another for of satanism believes the bible and everything it says but choose to fallow Satan and his army of hell. These satanists are/where common on the black metal scene especially in the 90's. Satanism can be related to Christianity and Judaism because of its extensive branches each believing very many differences.
Satanism is by far the most misunderstood religions.

The most realistic religion on the planet. It preaches belief in oneself as the ultimate god. While true Satanism has nothing to do with Christianity(except to point out Christianity's obvious flaws), it does reference it a lot in order to clarify its own belief system.

Basically the main difference between Chritianity and Satanism is that Christianity preaches that you should harm no one, not even your enemies. Satanism, on the other hand preaches that you should harm no one unless they cause, or intend harm to you, in which case, you should kick their fucking ass.

The only real flaw in Satanism is it's name. If it were called something else, it might be more widely accepted by other people.
Satanism is a great religion, but would be a lot more popular if it was called something else, like maybe Humanism...

Satanism is very different from the worshipping of the Christian Satan, or demons. It's an atheistic philosophy of life, celebrating man's carnal instincts, and not to supress your indulgences. Anton Szandor LaVey was the first person to give this way of living a life, and he chose Satanism. If Satanism has nothing to do with the Devil or demons, why does it have the word Satan in it? Satan is a symbol for indulgence, for what other people perceive as "evil". We believe that man is God, so birthdays are the most important of the Satanic holidays. The other Satanic holidays are the Solstices, and Walpurgisnacht (Hallow's Eve). The symbol of Satanism is the pentagram, with the head of Baphomet in it. There are nine Satanic statements, and eleven Satanic Rules of the Earth. The Satanic Bible was released in 1966, written by LaVey. It contains the books of Satan, Lucifer, Belial, and others. As well, it contains the Thirteen Keys, translated by LaVey himself. So, in short, forget what people tell you about Satanism. It's not doing drugs, killing children, or sacrificing animals, it's a celebration of indulgence and man's body.
"dude, you worship the Devil!"

"same thing!"
"go read the Satanic Bible, you ignorant wretch of a human being"

Often related to Evil or Cruel when the religion isn't actually known or understood. It's not full of goat raping, animal killing, kiddy fiddling/killing or any sort of murdering unless an ADULT person actually deserves it.
This is because an adult person knows right from wrong, they know exactly what they are doing... If a person punches you, don't love thy enemy... Kick his fucking ass!!!
