In a sense I agree with you, Jim is head and shoulders over these charlatans that shoehorn ET into any and every tall tale that they possibly can. They care not for math, nor do they care for any prosaic explanation, as we can see for the example you posted concerning Buzz Aldrin whereby his words were altered to specifically offer a more nefarious scenario than that which actually happened. Boon put it quite well that the crowd you speak of are by definition an oxymoron. You will notice not a single one of those snake oil salesmen have the gumption to come in here and speak to the people, like Jim does, and lets face it, that is because Jim has absolutely nothing to hide. The field you speak of is one of trickery, charlatans, new agers, all the sellers of fantasy and dreams, not a one with their feet firmly on the ground with a proper grounding in flight mechanics who actually can start to make sense of the anomalies that confound the everyday person like Jim Oberg. Whilst Jim is probably not very good with fictional ET tales, he can tell you how a rocket engine is designed and what it's behaviour will be, and we are extremely lucky to have him on board to help us laymen understand these intense and complex processes. It is merely a shame that a few miss the opportunity to learn from a true qualified professional with a wealth of experience when the opportunity has been obviously placed under their collective noses. The old, you can lead a horse to water scenario I guess.
In short, if one is interested in keeping the mystery and never learning a thing, I could see why one would wish to avoid Jim Oberg and stick with the snake oil salesmen in the field. That is certainly not Jims field.
