It's overlapping bullshit.
C'mon. This "doctrine" -- and it pains me to even call it that -- is the abso-fucking-lutely stupidest thing the WTBTS has ever come up with, and they've come up with some really stupid shit!
In a way, it's brilliant: it shows how gullible and desperate the average cult member is to belong to something no matter how dumb and to follow their leaders unquestioningly and uncritically. All the leaders have to do is come up with something -- it apparently doesn't matter how ridiculous or illogical it is -- and the "sheeple" will ooh and aah and say, "Oh. Yes, that's right! Look how wonderful Jehovah is!" and keep right on following no matter what.
Let's review: It's a cult!
Aren't we glad we have superior personal integrity, courage and critical thinking skills to call bullshit on this kind of nonsense!
Does that sound arrogant? Nah. It's just the truth, the real truth.
