"Trained",or perhaps brainwashed, appears to be the optimum word here to describe rationalizing, assumption, presumption, and irrelevance to truth, or fact, by Geotech skeptics.
I'm glad that I haven't read the electronic text books, that tell me what is possible, or impossible, to do.
Not knowing in advance what works, or doesn't, allows me the freedom to learn from my personal experience of trial & error, without bias, prejudice, or judgement ,and enjoy the benefit of knowing and practicing that what the skeptics say, can't be done, is neither fact, or truth in this case.
Thanks for the skeptics miracle moment of rational logic, and instance of common sense. Dell
