RHA, in regard to what you said about commercial beekeepers not having trialled TF, you have assumed they haven't and unfortunately, you have assumed wrong. Have you, for example, checked to see if I am a treatment free beekeeper? You come across as thinking the commercial beekeepers know little more than you do. But they are aeons apart. It's obvious why few of them say anything here though.
As to what you said to Specialkayme re lecturing, much of what you say sounds like a lecture, to me. And if that's how I hear it, I'm sure there will be others. And in fact when I begged to differ with some of your opinions, your reaction was hardly that of somebody prepared to learn.
