I think it makes sense that "demons are inherently evil" becomes a loaded idea when you look at who tends to wield the "demon" accusation against whom. A hegemonic Christianity overwhelmingly accuses marginalized groups such as LGBT people, neurodiverse people, feminists, members of minority religions, and communists of being demons or possessed by demons or aligned with demons. That creates a basis for even something as seemingly tautological as "demons are always evil" to be read as right wing-coded.

I think people are huge nerds

Yeah, guilty
