It looks to me like there is a great amount of over interpreting Dr. J's post. He was in fact, giving his opinion on what he had been reading on this thread, and on the playing of Scott Hamilton.
Rather than arguing against people expressing their opinions, my take is that he was , at least in part, saying it would be beneficial to get beyond a narrow set of preconceived ideas about styles, etc. Listen to the music with an open mind and then evaluate it and feel free to express your opinion.
