"It's not a question about if you agree with written Satanic statements or not. It's about what you naturally do as an individual... since man is a tribe..."
What your silly head cannot grasp is that the standards or rules don't have to be written. You mentioned tribes but tribal societies have their oral traditions. These are the rules that regulate the tribe's life and are passed from generation to generation. These so called unwritten honor codes let differentiate tribe members from outsiders. You don't live in a tribal culture but you're part of the Western society that is highly individualistic. Satanism is one of its expressions. It doesn't have clear standards or rules, like the religion has. It doesn't have an oral tradition like a tribal society has. And it doesn't have clear criteria for the label because everyone has different imaginings as to what Satanism is and what it means to be Satanic. The only thing that you have is various organizations setting their own rules of admission and various individuals creating their own "personal philosophies." If there is no consensus when it comes to the objective criteria for the label, you can't call anyone a pretender or faker. Or you can but you will be pulling shit out of your ass.
"You are called Satanic if you simply behave like Satan."
Satan is mentioned in the Bible only once, in the book of Job. The word means the adversary of God's chosen people. By that vague definition and depending on how you understand "God's chosen people", TST fits in fine because they oppose Christians and the Nazis fit in too because they hate the Jews. The rest is Milton, Divine Comedy, folk tales and modern horror movies. Satan stimulated people's imagination for centuries but one would have a hard time coming up with a concise meaning of the word. Even if one goes by the dictionary definition that Satan is an accuser or God's enemy and humanity tempter, then that also suits TST and Nazis.
"The pretenders wouldn't do that by nature."
I already told you that TST has its gatherings, ceremonies and communities in the form of chapters. It was them who revived the idea of grottos, stressing the need to meet other Satanists and creating the communities with the aim of socializing, conducting ceremonies and engaging in social activism. They have basically the same mindset as you. So what's your damn point?
"That was one of the primary reason why LaVey created the church of Satan."
On the contrary. One of the reasons why LaVey grew disillusioned with the church clergy and started selling titles for money, also disbanded grottos was people treating their membership as a sort of an achievement instead of focusing on doing their best in their life. This was the kind of people, like you, psychic vampires in need of some community which they could belong to and desperately cling to, thinking mere membership and the label makes them the "alien elite."
