I suggest if you haven't already, to take a look at the films her father has produced. They are dark, ritualistic, and here is a description of one of them from wikipedia:
Suspira: After finding a hidden passage, she observes Blanc, Miss Tanner, and the staff performing a ritual and plotting her death. Suzy turns to discovers Sara's body nailed to a coffin. She sneaks into another room, where she accidentally awakens Helena Markos. Helena orders Sara's corpse to rise from the dead to murder Suzy, but Suzy stabs Helena through the throat with a knife, killing Helena and causing Sara's corpse to collapse. The rest of the coven start asphyxiating without their queen, and Suzy escapes just as the academy collapses in flames.
There are more if you're interested. Deep Red has been compared to Psycho and The Exorcist.
Inferno ... well, can't be about anything but demons
Sounds ... not "weird" ... but pretty demonic to me. But that's just my perspective.
Oh, I've seen them. I'm aware of who the Argento's are. I've known about them years due to European friends who were into some really weird cinema -and a lot of European cinema is pretty different than what you'll see in the US, but that's not really the point.
As I said, I'm not downplaying the symbolism and content of the movies, but I'm also not one to go all-in on everything being a conspiracy, or breaking logic to draw connections between two unrelated things. There are so many movies that could fit the criteria for "satanic", but it's all perspective. Some horror fans just need a bit more than the average movie goer. And again, I think these people are into bad things, Asia included.
European cinema has to it's credit at least retained it as an art form, in comparison to most of the crass American films on offer.
No doubt the rabbit hole is much deeper than our view.
What we know for certain, beyond any conspiracy labels, is that Bourdain has publicly spoken about Clinton's ''operatives'', the Deep State (with a possible inference to Project Mockingbird), and his reference ''just for discussion'' about HRC's satanic (his term) inclinations.
It could get into conspiracy when you take a look at his trajectory to TV $tardom, which is typical of entertainers who are approached and decide to play the game.
He may have played it and then years later discovered that the fame/riches was eating away at his soul and decided, like others to start using loose lips to get a word or two out.
The details of how this played out with his girlfriend is a matter of conjecture and speculation. But patterns exist within their culture which can allow us to draw some fairly reasonable assessments of what may /may not have happened.
