"So please do not dismiss me as an unread, inexperienced ignoramus"
Why not?
My grandfather was a RFC pilot in WW1, my father a RAF pilot in WW2.
I claim no special knowledge of fighter pilots as a result.
So just how does your family history give you the unique insights that you claim? Is is a form of interfamily osmosis or telepathy that this knowledge is derived from, or merely a subterfuge to claim false credibility?
Personally I find the argument arrant nonsense, but you resort to it frequently. Any fool can read a book. Understanding the content is more of a challenge, even more so when attempting to verify the content.

I feel if you need to bring family history into the equation to add credibility to your claims, then your argument is becoming very thin.
