I didn’t question the author’s intent but stated that a text’s meaning isn’t limited to it or by it. There are about 10,000 interpretations of Hamlet and you can bet that Shakespeare didn’t intend all of them and would take exception to most of them. That doesn’t reduce the interpretations.
The point is to reach an understanding of the author's intent. What somebody spirals off to later is his own business including being declared heretic and excommunicated.
