what demons are, an explanation of Hell, the Four Crowned Princes of Hell, lesser demons, and guardian demons
Technically the Jewish ways of how Demons are shown have ceased to concern us and so we will be more and more detached than the collective Jewish imagery of the thing and Satanism will no longer be about "come on, let's explain that Demons don't have an evil role, maybe they are even pleasant, etc."
We no longer have to justify ourselves because Jews accuse us now that Jews no longer count for anything in the world. I would adjust the focus and make a book about how our Gods take care of us rather than how Demons are not evil monsters as Jews say, etc. Maybe a nice story of how Zeus seeing this beautiful child takes care of him and decides to charge the Gods under him to follow that child in different situations and show the right loving guidance to do things, but preserving free will.
Children will not find themselves like us having to dedicate their souls wondering if by doing so they will go into eternal flames or if they are worshiping the Lord of Evil during the Initiation Ritual as we did. They will quietly dedicate their souls if they are willing to accept the presence of the Gods in their lives and decide to improve themselves on this path to perfection.
However, these arguments you mentioned are right because are actually part of Satanism. When you talk about what the Gods really are, it would be better to talk about their universal roles in the Pantheons and not how "yes, Astarte, however, she is not as she appears in the grimoires, but she is a beautiful and kind Goddess," there are really many more things that the Gods are and embody besides "no, it is not true that he is as the Jew says in the grimoire."
Likewise, people need to understand that Lesser Demons are important and do not deserve to be underestimated because they have always been really loved by peoples and appreciated for their care and powers. Think about Pazuzu, beautiful things could be said about him without repeating the usual "he appeared in The Exorcist movie, but he is not evil, etc."
There are also Gargoylle-like Demons who care for the souls of Satanists, etc., and they deserve a thought now and then. Just as people need to know they can rely on the Guardian God without wondering the usual story about whether they will be possessed as told by the Church.
