Well there are many Pagan and other religious groups on DA. This group should be a home for Satanists on DA. There are still some misconceptions about Satanism today, even though we are no longer living in the Satanic panic anymore. However, It is not our fault, and we do not need to justify our path to anyone.
I had a lot of discussions with believers in the past, mostly people of the Christian cult, and I learned from real life experiences that arguing with them is not worth anything. Weak-minded individuals can never free themselves to find a purpose in life without this blind-faith that breeds nothing but weakness, fear, guilt, and sheep-mentality. Satanists should not associate with the Nescients of this world, regarding the knowledge we have and we should not push anything on others. It goes against the Satanic tenets to enlighten those who do not have the strength and the Will to evolve. Some people deserve to be devoured by their weakness. It is natural for the strong Animals to help only their kind. Therefore, we must help only those who have the potential to know thyself.
You are born a Satanist:
I personally believe that Satanists are born, Satanic since birth! You do not have to join the CoS or be initiated into any sect or temple, because it is just the way you are born and it is your natural path to be a Satanist. I just realized this naturally myself. In the Book of Lucifer, Anton LaVey said the following: "It has been said "the truth will make men free". The truth alone has never set anyone free. It is only DOUBT which will bring mental emancipation. Without the wonderful element of doubt, the doorway through which truth passes would be tightly shut, impervious to the most strenuous poundings of a thousand Lucifers."
A Satanist is someone who questions everything. He/she is not a blind follower, or blind worshiper of Satan. (Most Satanists do not actually worship Satan.) Whether the Satanist is a theistic or atheistic does not matter as long as he or she understands that all the power comes from the Self (Self-awareness), and not from an external source. The Right Hand Path glorifies a God 'outside' of the Self. On the Other hand, self-deification is the essence of the Left hand-Path. The Adversary existed in almost every culture, and he has always been that rebel one who will never bow down and worship anyone. He dwells within our subconscious. The Adversary is not necessary an external being. "Who looks outside, dreams; who looks inside, awakes. - Carl Jung." Do you want to open that third eye, or to live in some Satanic fantasy is the question today.
"Non serviam." is what the Satanist stands for. Even though, I'm not what people refer to as a LaVeyan, I believe the Satanic bible is a necessary foundation for Satanism. It is not the perfect guide, or the best religion that defines Satanism. Anton LaVey was truly a genius, but Satanism existed way before Anton LaVey, and it has evolved dramatically today. The Satanic bible is a beginning and a great basis to know if you are a Satanist or not. I happened to disagree with Dr. Anton LaVey on few things, and that is fine, because Satansim is a religion of the Self. I tend to focus more on consciousness, spirituality, and ceremonial Magick, than philosophy or social Darwinism. I happened to be the Spiritual type. However, Satanism without a philosophical foundation is nothing, but fantasy. That is why the Satanist must have philosophical, historical, and spiritual knowledge all together in an occult system of her own. Arguing with each other on who is getting it right is destructive and it really benefits the enemy. There is no right or wrong, if what you do works for you. It is as simple as that.
If you are on the Left-hand Path, then you are by default on a Spiritual path. Knowing yourself in the darkness is the only light in Satanism. "One does not become enlightened by imagining figures of Light, but by making the Darkness conscious.” - Carl Jung. It is not a light of good vs evil, but a self-illuminated light. As a practitioner of the Left-hand-path, I call that the Black Flame. Thelemites call it the True Will. It does not matter, because you alone who create and destroy in Satanism.
In short words, Satanism is a path or a religion of Self-liberation, based on a philosophical and darwinian foundation. The Satanic philosophy truly works, and I'm a witness of the Satanic power. Satanism encourages indulging in the natural desires. However, every power that is not balanced by self-discipline leads to destruction and Satanism is not an exception, for it is the natural law. In Satanism, it is your responsibility to know your limit and when to stop.
Blessed are the destroyers of false hope, for they are the true Messiahs,
Cursed are the god-adorers, for they shall be shorn sheep! (The Book of Satan.)
Self-preservation is my highest Law!
