I don't disagree with your points, but my problem is not specifically about Dobson (or any individual history) but about a perceived attitude of every claim, every remembrance, every statement is true and valid because there is not objective reality and nuances, subtleties and details are not needed.
I can't speak for anyone else, but my point is just the opposite: that nuances, subtleties, and details are critical because the objectively reportable facts don't tell you much. But also that those nuances and subtleties will be filtered by the person telling the story.
At a much smaller scale, consider any aikido technique. There's what nage is actually doing, as it might be measured by an objective device like a camera or a motion capture system. There's what nage thinks he's doing. There's what uke feels. And there's what a human third-party observer sees (or thinks he sees).
