I don't post a lot here anymore, but this thread caught my eye. Jim, you are well educated so I must ask did you not question anything that your professors ever said to you? Your field is not without change and lots of research continues to be performed that changes the state of knowledge over time. Given this, why do you feel that it is so bad to question advice given? As an educator, my PhD is in higher education, I find it rather boring when students sit and listen to what I say without any comment. I personally want students to disagree, at least it gets people to pay attention and this promotes learning, not the blind faith that what I say is the true word and there aren't any other possible alternatives that exist. The way that we understand our work today is quite different than what was accepted practice in the 1940's,50's, 60's and even 70's. There is no doubt that the art has advanced to the next level and has brought our understanding of how things were done to the past much closer than was true in past years. Still, I am quite positive there are things that we don't know and never will if new ideas and methods are not continually explored.
This is not to say that all methods are correct and should not be corrected when seen, but please leave out the blanket statments that all those who oppose are unworthy of your attention because that is counterproductive and not within the spirt that this forum was created. Nobody ever said that being an educator was simple, it takes the patience of a saint at times. But keep in mind that we all start somewhere. Some of those who ask the most seemingly disrespectful questions today might be the builders that others look up to tomorrow for advice.
So there is my 2 cents, feel free to roast me for it, perhaps it will get an interesting discusssion started and the learning can continue.
