Argument for arguments sake is worthless rhetoric.
Ken, you're being too kind in attributing either skill or genuine belief to our mutual friend's posts.
It is one thing to argue on the basis of experience, but that can only carry the discussion so far. As appraisers, we observe, analyze and report. We report the behaviors we observe in the market in the context of principles of valuation. These POVs are well understood across a broad range of economic theory. It is the application of such POVs which advance our arguments, not our experience, designations, education, or even are ability at rhetoric.
In the arguments made by our friend, in this and other threads, where is the reference to such POVs. What basis in appraisal liturature or valuation theory does he cite for his arguments? None. Surely with his long history of education and achievment he must have accumulated some body of reference to which he might refer.
Further, contempt for those with whom one would contend is not a basis for either mutual respect or philosophical discourse.
I am amazed at how many threads devolve to this state from this fellow. I am quite sure that those reading these posts, who may be inclined to agree with him on occasion, must too have second thoughts regarding the temperment and tone of such communications.
