A lot of the people in the underground horror / extreme horror scene are legitimate satanists and occultists, I'm talking straight ritual sacrifice shit. These films are explicit rituals too, watching them can have negative effects on its viewers. 

Some primary figures:
Stephen Biro
Marcus Koch
James Gunn
Lloyd Kaufman
David Firth
Ryan Nicholson
James Creamer
Jimmy Hellfire
Bill Zebub
Fred Vogel
Shelby Vogel
Andrei Iskanov
Brian Paulin
Ruggero Deodato
Lucifer Valentine
Herschell Gordon Lewis
Jorg Buttigiet
Tom Six
Eli Roth
Olaf Ittenbach

Horror films are popular because they appeal to our primal instincts (sex and death). Dubbing them 'satanic' is ridiculous unless you want to name the human species 'satanic.

Added to which, Lucifer Valentine is a nobody who tries to make money off an edgelord persona. Gullible people like OP fall for the schtick. I recommend watching some GOOD horror films; then maybe checking out the DVD/Blu-ray/4K special features to see how and why they were made. Watching some 'making of' stuff might help you realize 'it's only a movie... it's only a movie... it's only a movie.' :D

You're correct in that we are ruled by satanic elites. You're pointing your finger at the wrong culprits, though. The whole craze in Great Britain about the 'video nasties' was about having a convenient scapegoat to take the blame for a sick society. They did the same thing to video games in the 90s. Media consumption is not correlated with violence.

It takes two to tango. Everybody is a jew* in today's world. They all fall for their safety words and mantras. They all believe that so long as they act according to, or in 'legitimate revolt' trademark**, they are the good boy and thus will be valued by God. 
Not knowing that I am implies God. Not knowing that this validates them and us. Not knowing that this invalidates parroting... 

>*believes that they have bought it all, believes what they have been taught; complies and takes that as morality - like Abraham who tortured his own son
>**contrasted to phariseanism, the modern anti-sjw, sjw paradigm is a perfect example. Nobody is authentic.
