It's about the orthodox/theistic satanism crap, especially the prayers on an album. The whole ritual/prayer thing is a stupid gimmick and their music is tech-death/mathcore twisted into black metal. I find the music aggressively boring.
I hear you. I can't disagree except in opinion. The music is very engaging to me.
Actually, I think DSO calling themselves black metal is a disservice to themselves. Then again, there are those people who think that black metal is just music about Satan, in which case DSO would be taking the genre to its logical extreme. But if we define black metal by technique and purpose, DSO is some mutation of metalcore.
Is it a logical extreme? Black metal has never really been about theistic Satanism, but Satanism was invoked as a concept that laymen could understand. It quickly became a casual stay of laymen in black metal, but it was essentially a conceptual gateway, an appeal to the layman's understanding of it, not an orthodox, theistic, or literal religion. The logical path was to abandon this as its meaning was distorted and lost. It's a farce, no more than an aesthetic or fashion statement. For fucks sake, the year before DSO decided to really pick up the "Orthodox Satanism" nonsense, Anthrax had an album cover of them with pentacles on their chests. Satanism was a farce that became an even more trivial gimmick and joke, and these clowns took the joke too seriously.
Satanism is mythology, not ideology. Imprecation's latest album invokes it properly.
Black metal has never been about Theistic Satanism, you are right. Satan was a handy catch-all symbol for a generally adversarial attitude. The trope of occult imagery and themes became a sort of self-referential, insider joke in metal as the years passed.
So it is extreme (though maybe not logically so, at first glance) to try and invert that attitude of "we know this is a joke, it's not scaring anyone any more, it's par for the course". Theistic Satanism is not a new thing by any means, and I think DSO applies the matters of Satanism to their lyrics for more than just shock value. Shock value is dead; Anal Cunt trumped everything; smart bands of today realize that the brootal slam bands are foolishly overextending themselves across ineffective tangents in a hopeless effort to maintain relevance, because they know that Carcass used cheap tactics to scare people a in the past and don't know where else to proceed from there.
Beyond that, the methods and meaning of Satanism that DSO outlines (explicitly or implicitly) in their lyrics and melodies do not suggest lack of knowledge or mere infatuation with symbolism that appears "dangerous" and "edgy". My guess is that the guys involved in the writing are aware of the history that precedes their ideas, and have a firm enough grasp on that history to effectively express the concepts (mythologically and ideologically) presented by traditional Satanism.
All that considered, I conclude that DSO's presentation of a literal Satan in the mythological and ideological (because Satanism is, in essence, both, as mythology and ideology are not so easy to separate) sense is not just a matter of shock value or general cluelessness. But, I see how that is an easy assumption to make if you have already made up your mind that Satanism always has been a joke and always will be.
Like DSO being identified as black metal, it is also too bad that this "Theistic Satanism" must be identified with Satan at all. The Horned One has a lot of baggage attached to his name.
Semantics! - would that you were not!
I have to say though, not looking forward to a future where you mount a one-man personal defense of every band this board loudly hates (kidding, kidding).
The future looks bleak.
