a building with no intrinsic spiritual value in itself - that'd be idolitary
Let's compare this w the attitude and actions of ot jews to solomons/herod's temple. The temple was said to be the dwelling place of jehovah because of the arch of the covenant w the hovering shekinah light. Before it's desrtruction, it is understandable that jews prayed toward the temple, to the shekinah. After the babylonians destroyed jreusalem, there was no more arch/shekinah, yet the temple that pagan herod built for the jews was still considered sacred. Even jesus called it the house of my father, when he attempted to clean it up. Was this herodian temple devotion idolatry?
In a king hall dedication, what is dedicated, and to what is it dedicated? Obviously, the building is the object being given over. The next question is, to what is it dedicated? I would say that it is being given over to an activity, ie wt training, study and related activities. These activities have the aim of spreading wt propaganda, raising money, gathering new recruits. Therefore the building is not truly, directly dedicated to a god, jehovah, but to activities of the wt corporation. That would explain the ease with which they can dispose of their buildings after they have become redundent.
