I was a young naive idiot long ago, joined a Wicca group, just was not for me. I started reading some books, which I brought in a occult shop. You can only learn so much out of a book, and some ain't worth the bother.
And now, I write my own. I got to many journals, since i started writing at 22 yrs old. Now 43. Satanism philosophy was the main core of my experience, and practice.
Meeting people in society, mainly the occult, and slowly my knowledge came together. I do not know everything, never will. I am still learning now.
Satanism, has changed now, many newer forms and philosophy. And more groups.
