Fisherman,
How does that establish that Rome is the Rev HOB or debunk WT interpretation that it is WEFR?
The point of the observation is that a faulty methodology yields faulty results. Jehovah's' Witnesses have provided ample proof of that.
Have you considered the possibility that the value of Revelation today might be primarily historical / instructional rather than a collection of prophecies to, for and about Jehovah's Witnesses themselves?
