Although they were clearly full of crap, there's no denying that the old guard on the Governing Body really knew how to twist some stories by tying together random scriptures that were intentionally mistranslated just enough to make the claimed interpretations believable to the gullible.
They were insidious men, but the old guard had some genuinely intelligent people -- they just chose to use their intelligence for evil instead of good.
I will say that I'm a person who frequently warns people to not mistake malevolence for stupidity. People do it with politicians all the time. "Trump is stupid." "Obama is an idiot." "Hillary is incompetent." "Bush is a nincompoop." None of that's true. They all know/knew EXACTLY what they are/were doing.
That said, however, this current crop of Governing Body men gives no evidence that I can detect of being able to engage in any type of deep thought. In watching them over the years I have been unable to spot any occasion that I can point to as evidence that they have any clue what they're doing. Everything they do is short-sighted and reactionary -- telltale signs of people who are not cognitively gifted.
I think there's simply nobody left who can create a book full of new, yet kinda-sorta plausible, horse crap. Everything is just retreads now.
