“OK, I do —NOT— consider Luther, Knox, Calvin, and the Protestant theologians in the 1600’s & 1700’s to be heretics. They taught a preterist viewpoint, with which I agree.”
... why wasn’t this idea taught before the 1600s??
“and —IF— the temple had already been destroyed by the time Revelations was written, Revelations would have made note of it.”
... Then it would follow from your theory that all books would refer to every major event that proceeded the inspiration of the book - the fall, the exodus, the captivity, etc.
... this is demonstrably false.
... far better to understand and acknowledge the purpose of the book and the type of literature, than to impose a standard not adhered to in Scripture.
... in short, your argument is built on a faulty presupposition. I don’t find it consistent with Scripture. It presupposes a fact it wishes to be true in order to support an idea it also presupposes.
Now, if that idea brings you some kind of comfort as a personal practice or personal idea, fine. I wish you luck with it. Unfortunately, you will miss out on the richness of the revelation, as God unfolded it.
Still, it is your call and I wish you well.
