I'm not sure this answer will cover all the nuance of the question, but I'm gonna type anyway.
I wish I could find the passage, but Paul speaks to this "inability to the point of impossibility" to express a Spiritual thought to a carnal mind, addressing one of the churches. And I'm sorry, but "theology hobbyists" are expressions of a carnal mind even if they are in possession of some sound teaching/doctrine. Spiritual truths must be lived, and that is very very hard. So my "words" just sort of lay there flopping. Of course they sound silly when you have to dumb down deep, hard-won, lived treasures for the ears of minors. But you don't know who's day it is for the fruit of the foolishness of preaching to sprout.
On the other hand, we are admonished to "correct a brother at fault" with "meekness, considering ourselves lest we also are tempted". It's easy--at least it is for me--to attempt to over-correct and try to be the savior and say things that dig a hole of my own. Ray was a good example. He answered often silly, "milky" questions with something of an innate sense of how "spiritual" to push the discussion. If I had been answering those thousands of emails I would have let no opportunity to radically reorganize the spiritual lives of the questioners pass. And that, in itself, is silly.
Finally, this. I don't want to launch into a big exposition right now. And I won't at all unless you want me to. But I think what you are talking about is part of what is being talked about in Romans 7, decently translated. I don't think Paul lacked boldness or wisdom in any way, but I think he ran into his own limits in expressing it.
In your case, however, you should consider being ashamed of putting your "own “exegetical” explanation of the topic" out there in public for everybody to see. That's just not right!
Ecc 9:13 This wisdom I saw also under the sun, and it is great to me:
Ecc 9:14 There was a little city, and few men in it. And a great king came against it, and besieged it, and built huge siege works against it.
Ecc 9:15 And there was found in it a poor wise man, and he by his wisdom saved the city. Yet no man remembered that poor man!
Ecc 9:16 And I said, Wisdom is better than strength; but the poor man's wisdom is despised, and his words are not heard.
Ecc 9:17 The words of wise men are heard in quiet, more than the cry of one who rules among fools.
Ecc 9:18 Wisdom is better than weapons of conflict; but one sinner destroys much good.
I've known you a long time, Porter. I know you wrestle with the angel.
