Interesting points.
As to the poor research, I meant mine, but appreciate your kind comments as to how the supposition came to be. But, it came as a surprise to me (hadn't known of 'Jr's' situation either) and I should have been more attentive.
As to my "falsely" assuming that you were "researching something" - I 'assumed' nothing of the sort in particular, merely having believed that one would know of what one spoke of here before asserting something like that, that's all.
Not to condemn for it, mind you. But the point is that it is always in our own hands here, post-by-post, as to whether we elevate this place to some level of academic integrity, or allow it to sink into mere blogging where casual statements come and go with little regard. In this case, the point of Nimitz' suicide was more than a passing thought - it was at least obliguely seminal to the notion of his potential impairment with regard to his statements on Earhart and the Marshalls.
I tend to 'assume' the former intent - that of raising the status toward academia here, as it is more befitting the charter of this forum (not blog) as I understand it. And I thereby take points such as you made as fact, i.e. 'well enough researched' - as would rise to the basic rigor I tend to see here; thus I also avoid 'false assumptions' as best I can - but am prone to error, just as you are, of course.
So I think it is not a "false assumption" in this environment to do as I have, but a product of an expectation. Shame on me for not having questioned it more by reason of my own mental blank at Chester Nimitz having taken his own life (had not known of Jr's plight, it came as 'new' information and it seemed out of character of what I had known of 'Sr'; alas...).
As to Nimitz' own comments regarding the Marshalls - for all I can know, his comment may have been truncated: perhaps he finished with (an unspoken?) - "...because I know that's what you want to hear, but it isn't so...".
Mists of war and adventure and time and of old men, I'm afraid.
