You really need to read more carefully Ken.
Since that is, at this point, exactly what am thinking about you, there is probably not much point in taking this further. However, I will have one more go, and I will base it on your own metaphor, to simplify the reading task.
HCB is the Brain Surgeon. What we are talking about is his approach to brain surgery - as a matter of fact. The way to decide that is to look at his work, read his utterances, consult his colleagues etc. We weren't talking about the best source of advice on how to do anything. If I wanted to get advice about how to practice photography, or brain surgery, sure, I would go to a photographer, or a brain surgeon, or maybe a text by someone who had talked to a lot of photographers and brain surgeons. But Isaac wasn't giving advice about how to practice photography. He had a different view to yours, or, maybe, he was trying to probe your view, on whether HCB was stealthy, sneaky etc, in his practice.
Setting aside the semantics, which took up too much of the argument, my own view on that subject is not far from yours, and I think your notion of being inconspicuous is persuasive in relation to a lot of fine work. However, in assessing your view, and Isaac's, on what HCB did or did not do, I have no interest whatsoever in your photographs, or in Isaac's*. Instead, I would go to HCB's photographs, and to what he said about his practice, and assess your respective views accordingly. On the other hand if I wanted advice about how to do street photography, I would certainly want to hear from photographers whose work I admired - and also from people reporting the views of photographers whose work I admired. But that was never the subject - was it? It certainly wasn't the question I asked in the original post.
*Just to clarify - with an irrelevant point - I like many of your photographs.
