I know you addressed that to OKCS, but since I've noticed that OKCS has expressed his Christianity several times, I'd like to input on that.
The "Octopus" is "Evil". I don't mean just 'bad', I mean EVIL like in Satanic. We're in a death battle that has Satan supporting his minions in supernatural ways. Some of it involves death, some ruining of people's lives, and creating and re-enforcing Fear.
Whether Casolaro ever voiced or noted that Head of the Octopus is not particularly significant now. If he'd written his book and included that observation, it would have been handily dismissed by those who Choose not to believe that. If you do, that's fine by me. I'm not an Evangelist. If you're an adult, your soul is in your control.
But any others who read this need to mull my comments, and try to come up with a non-faith based answer to why the Blindness that is now obvious is adhered to in spite of massive evidence that what I've pointed out is the most viable answer.
