I've never examined another well known anti-Org site's beliefs before, but having just looked at it via a link in a current post, I immediately noted the WTBTS/G.B.'s favourite phrase - "kings and priests" - being parroted!
Reasoning purely on the Bible, the Greek word "basileus" can be translated as leader of the people, prince, commander, lord of the land, king. How many kings (according to scripture!!) have/will rule the earth at any given time? God first, then Satan, then Christ, then God - only one at a time!
If 144,000 Melchizedek wannabes get their wish, then Paul's unique comparison of Christ with Melchizedek (8 times) at Hebrews chapters 6 & 7 is totally worthless.
Psalm 45:16 tends to shed light on the subject - "Your sons........You will appoint them as princes in all the earth."
The inserted word 'kings' at Revelation 5:10 has no foundation, logic, or corroborating evidence to support its usage - as it is translated in the KJV and subsequently plagiarized by the NWT.
Because someone is described as "reigning", does not mean they are kings - e.g. Daniel, Shadrach, Meshach, & Abednego all reigned at one time, but not as kings.
Just my take on the apparent agenda to perpetuate the old "kings & priests" ploy.
