That's a fair response. My only objection is that you seem to think there's something wrong with people speculating about unexplained phenomenons or unresolved history.
No, not at all. Theology, by necessity, is entirely speculative. The UFO phenomenon (which I have experienced) is a genuine phenomenon, but what it is remains entirely speculative. Virtually all the phenomena with which psychical research deals (a number of which I have experienced) are well-established, but what they are and what they mean remains entirely speculative. Ditto with the Shroud of Turin and the NDE phenomenon, another two of my pet interests but also largely speculative. I speculate, speculate, speculate along with everyone else. But there is rational, logical speculation and Gee Whiz, True Believer speculation that is driven more by cognitive bias and wishful thinking than evidence and rational analysis. Since I share some of the conspiracy-prone mindset myself, I (thanks largely to my legal training) make an effort to stay in the ballpark of evidence and rational analysis. All areas of Weirdness, including the JFKA (in spades), are rife with folks who simply aren't thinking clearly.
Speculating about UFOs or the JFK assassination harms no one. Millions of rational and intelligent people aren't convinced by the LN narrative and that's not likely to ever change given all the weird stuff in the JFK assassination and the investigations. So it is futile to keep trying to change people's minds.
Mostly it's harmless, but certainly many psychologists and sociologists think it isn't necessarily harmless. One could make an argument that irresponsible JFKA conspiracy theorizing has had some very harmful ripple effects.
As for myself, despite being a millennial, I personally have always been fascinated with the history and pop culture of the 1960s. The assassinations of political leaders in the 60s, the Vietnam war, the Manson murders, and the music of the 60s are often on my list of topics to research.
Well, hey, I lived through the 50's and 60's and once had a collection of
thousands of 45s that were catalogued and cross-referenced in absurd detail. I was a legend. I once had a woman I'd never even met walk up to me at a party in the 80s and ask, as a test, "Who sang Red Rubber Ball." I replied, "The Cyrkle - C-Y-R-K-L-E," and started reciting the lyrics. She walked away shaking her head and saying, "It's true, it's true." So start some inappropriate threads on THAT subject, which will be way more interesting than the JFKA!
