You can read the tenets of The Satanic Temple here.

Satanism is a really loaded topic, similar to anarchy. It evokes images in our heads due to the stigmas and social conditioning that don't necessarily correspond to the actuality of the idea. Supernaturalism, devil-worship, sacrificing animals, etc. aren't what Satanism is about. That's just what propagandists would have you believe.

"We understand the Satanic figure as a symbol of man’s inherent nature, representative of the eternal rebel, enlightened inquiry and personal freedom rather than a supernatural deity or being."

Satanism is a challenge to dogma. A challenge to the guilt we burden ourselves with for simply being human. A challenge to rise to your fullest potential from within.
