The last I remember was the Watchtower painted with a very wide brush and labelled all religions as part of Satan's demonic empire, Babylon the Great. That is, of course, with the exception of itself.
It doesn't matter that in its early history, the founder of the Watchtower had a fixation on the great Pyramid of Egypt and its measurements. If this had been another religion, I wonder what the Watchtower would say with regard to these origins? Can't you just imagine: "From its inception this religious movement was steeped in demonic prophecies. The great pyramid of Egypt was a product of Satan's first world power. To use its calculations as a basis of one's faith demonstrates that this religion had abandoned the sacred scriptures and substitued demonology as its holy writ..." etc. etc. etc.
The Watchtower should learn the lesson that Jesus taught: "Let him without sin cast the first stone." But then, the Watchtower doubts the authenticity of this scripture as I recall.
