Obviously they'd be dissatisfied with a law that identified Satanists as human beings. I mean, is this a scientific fact? Why? Sez who?
I bet they think they're defending human rights. When they don't even know what a human being *IS*.
As they view themselves as conscious products of the divine creative energy aka evolution aka serpent power by many ancients, then Satanists who believe they are human suffer from hallucinations caused by chemical and energy interactions in their grey-matter. Or in CS Lewis’s words: in rejecting the Creator and sustainer of their life and being they have stepped out into the void and are no longer human.
