It seems to me that you are arguing against yourself, in contradiction to your previous complaints: that is, you've pointed out and complained before about these myriad and absurd Rube Goldberg-type conspiracy explanations as to what happened but now turn around and say they have no explanation as to what took place, that it's just an attempt to exonerate Oswald and not give a counter theory as to what happened.
So which is it? Absurdly complex explanations or none at all? Rube Goldberg explanations or simply defenses of Oswald?
To be sure there are people here who seem to be solely interested in clearing Oswald. A sort of Mark Lane approach (although he blamed the CIA for the crime). But they are a small minority not a majority. And certainly if you go to other assassination sites they are filled with explanations as to what happened. Incoherent and contradictory ones, ones made entirely up; but at least an explanation.
Please, you are comparing Pre-Epiphany Me to Post-Epiphany Me, scarcely a fair comparison.

This is like reminding a new convert he was thrown out of a bar last Tuesday.
You have highlighted the entire problem with Pre-Epiphany Me. I loosely referred to "conspiracy theories" without realizing they
aren't theories at all.There may be extensive issue-specific theorizing, such as (for example) "why CE 399 cannot have done what the LN narrative insists it did." But this theorizing is not fitted into any coherent theory of the JFKA. The theory, to use the term loosely, is more in the vein of "the LN narrative has to be wrong because CE 399 is bogus." When one asks, "Please explain how what you are saying about CE 399 makes sense to you in the context of your own theory about the JFKA," you get crickets because there is no theory.
What I refer to as Rube Goldberg contraptions are not coherent theories - that's precisely the point. They are mishmashes of who bought the Carcano and how it got into the TSBD, why Bill Shelley was really a CIA guy, how Oswald was impersonated in Mexico City, yada yada, but the elements aren't internally consistent and don't add up to a coherent theory of the JFKA.
Tom Graves, it seems to me, has a coherent theory with the KGB. Perhaps the most coherent theory, to give the devils their due, is
Harvey & Lee. Armstrong did a staggering amount of research - the John Armstrong Collection at Baylor University is a priceless resource - and fitted it into a fascinating theory of two distinct Oswalds. I may think it's absurd in the extreme, but it is an actual coherent theory of the JFKA that the H&L folks promote and defend.
My post is actually an indictment of myself. By assuming these folks were interested in What Actually Happened and were arguing against the LN narrative in furtherance of some theory of the JFKA that they at least found coherent, I was giving them too much credit and just wasting my breath.
I'm making a pretty narrow point, whereas you seem to be accusing me of painting with a broad brush. In my original post, I specifically acknowledged the existence of coherent conspiracy theories. I addressed, however, the "very large and vocal segment" that simply wants to play Oswald defense counsel, has no coherent theory of the JFKA, and for this reason cannot be engaged rationally at the level of such theory. Like good defense counsel, they just sling mud and hope some of it sticks; whether it makes any sense is irrelevant. Some, certainly, aren't consciously playing Oswald defense counsel but are just mentally masturbating over issues like CE 399 because they don't know enough about the JFKA to do more than this and enjoy the game.
I would take issue with your last paragraph. In my experience, these folks are anything but a "small minority." They are a very substantial segment of the CT community, particularly on internet forums. YMMV, of course.
