So you admit rhis alleged plan has nothing to do with God's temple (which, after all, is in heaven) or prophecy being fulfilled.
I think that would be going a bit too far.
It certainly COULD be the fulfillment of prophecy. Time ALWAYS proves futurists right or wrong.
Is it possible that this temple could be torn down and another built in a future era that would be the one mentioned in 2 Thess 2. Maybe.
But, in any case, there would be a temple there, and when there is that would make a thinking man do some thinking.
