The predicament for people like me is that there is no neutral ground to dwell on; one either qualifies as a LN or a CT, an objective, open minded approach is very hard to maintain. Yes, I am critical of the Report but also of many of the conspiracy books. \
It seems like a binary choice to me. Either a lone gunman killed JFK or there was a conspiracy. If one believes the latter, I think that makes him a conspiracy theorist, i.e. a CT. I've always thought the term LN was a misnomer because I don't think legally Oswald qualified as a lone nut but since the term has been around so long, no point in confusing things by changing it now.
The 'overwhelming evidence' you say convinced you that Oswald assassinated the President hasn't convinced me. At least not completely. The unfortunate fact that the Dallas police allowed the suspect to get lynched prevented a trial, during which many of the questions I have could have been cleared up.
There's an adage that says never attribute to malice that which can be explained by incompetence. I just discovered there is actually a name for that called Hanlon's Razor. The DPD failed to secure the garage which allowed Ruby to enter with his handgun. Oswald was originally supposed to be transferred by armored car but when it tried to back down the ramp into the garage but it discovered it was too tall to fit. To help the armored car leave the ramp, the cop who was supposed to be guarding the ramp stepped away to hold up traffic and by happenstance, that's when Jack Ruby arrived and he just walked down the unguarded ramp. I don't think Ruby had any prior intention of killing Oswald. I think when he saw Oswald's face, he became enraged and shot Oswald out of anger. Admittedly, that's speculation but it certainly fits with Ruby's movements that morning. Had he intended to kill Oswald, I think he would have gotten there earlier.
Take for instance Oswald's supposed motive. If I remember correctly, the Warren Commission stated that Oswald resented all authority and wanted to make a name for himself and go down in history like John Wilkes Booth. I am unfamiliar with any evidence that proves this supposition.
Wouldn't it be odd for an individual who disliked authority to try to gain entry into the USSR via Cuba, where the authority of the government(s) is a major element of the organization of the state and part of everyday life of the citizens?
Determining Oswald's motive is pure speculation, even by the WC. Nobody knows for sure why Oswald did what he did nor do we need to know why to know that he did it. There's plenty of evidence for that. Whatever Oswald's motive was, he took it to his grave.
Another issue that puzzles me is the fact that Oswald himself, during his interrogation, and his acquaintances told the law enforcement officials that he liked President Kennedy. The various (would-be) assassins that tried to kill President Trump have not, to my knowledge, made similar statements - the same goes for the creepy weirdo who shot Charlie Kirk.
Mark Chapman got John Lennon's autograph hours before he shot him dead. We make a mistake when we expect irrational people to act rationally. If we did know why Oswald killed JFK, it probably wouldn't make sense to us. I said earlier that I didn't think Oswald was legally insane, but that doesn't mean he didn't have a loose screw somewhere inside his head.
An angle that was explored in a documentary on the Discovery Channel was the 'Cuban connection.' This story first popped up out of Mexico City right after the assassination. A red-headed Negro supposedly handed Oswald $6000 to eliminate the President. I think the evidence for this is flimsy if non-existent, but the Discovery Channel reinvigorated the story, albeit based on different 'evidence.'
The problem I have with these stories trying to connect Oswald's Mexico City trip to the assassination is that at the time, nobody could have foreseen months later that Oswald would end up working in a building overlooking the motorcade route. Not even Oswald would have known that. That's a problem for all conspiracy theories, whether one believes Oswald was an active participant or simply a patsy.
Oswald got his job at the TSBD 6 weeks before the assassination. That was before the motorcade route had been determined or that there would even be a motorcade. Originally, the Texas trip was only going to be a one day affair and John Connally was against having a motorcade because he didn't think they had time for one. It was only after the White House agreed to make it a two day trip that JBC dropped his objection to the motorcade. He was put in charge of planning the details including the site for the luncheon. It was the choice of the Trade Mart that dictated the motorcade would drive past the TSBD. The motorcade would have gone down Main Street in downtown Dallas no matter which site was selected but had one of the other sites under consideration been selected, the motorcade would have gone through down Main Street in the opposite direction and would not have driven in front of the TSBD. It was pure happenstance that the motorcade went right by Oswald's workplace and for Oswald, it became a crime of opportunity.
