Its true, there is a certain "brand" of fake, monotone, weird, and odd speaking that is "championed" by this modern version of the borg.
What the higher ups consider or think is a good speaker is what each speaker tries to emulate. Having the Org videos is also adding to this, as the R&F watch these vids of certain emulated brothers, and try to imitate them.
This is a by product of a Cult, where certain natural expressions of "freedom" are not allowed. When certain weird speakers happen to be "up there" in the JW hierarchy, it creates a lot of following the leader type crap.
They all look like robotic, weirdos, and this is who are "teaching" the rank n file, and youth of this Cult.
And, in answer to your question, YES they ARE clones. The Borg has a cloning factory in upstate NY. They are genetically splicing, robotics, odd facial gestures, haughty attitudes, and weird mannerisms, into the DNA of these clones.
Us "apostates" are the rebel alliance, and soon we shall be fighting the "Clone Wars".
