That is Extreme. Do you have sources for this belief?
Most any recent years Christian book on the topic will lay out the demon aspect in quadruplicate.
The other literature from more scientific standpoints in books and web docs--the better web docs--will lay out the other.
Some of the hardware stuff I get from my relative.
I don't file the info I read in any hardcopy anything or even on computer per se. It's a distillation of 40+ years of study.
I'm even giving away my significant UFO library to some Chritian brother with some knowledge of Dulce whom I know will not be hurt in his spiritual relationship with God by the books. I don't get into it with some Christians or others, for that matter. I don't want their spirituality with God being put at risk.
On the other hand, I think some need WARNED so that their spirituality won't be at such risk as many's will be when things really come out in the open.
BTW, which of my statements did you find most extreme?
