Part of the reason we're getting conspiracy theories like this is probably that John Podesta conducting satanic ceremonies is kind of plausible. He (or his brother, I forget) is friends with an artist who likes to carry out elaborate ceremonies involving blood and bodily fluids, and helps fund her work (possibly stuff that's less intentionally controversial, though). While that's technically not satanic, the need to qualify the kind of blood magic he's linked to makes it hard to have a sense of what's realistic anymore.
