Since no one is making that claim I wonder what you are talking about? It seems to me that you cannot have had much contact with scholars if this is how you think (and at least three of us have been involved in this thread so I’m not sure you have an excuse).
All scholars do is homework. Usually on a much broader and deeper scale and any amateur dilettante is capable of because we have much greater training and access to the necessary resources and a community of peers to sharpen our thinking.
Keep an eye out for the next issue of Contemporary Buddhism. The whole issue is devoted to the word vedanā. A mix of Buddhist and neuroscience scholars contribute a good deal of depth and breadth on the subject that I think you will find illuminating.
