You really should find a niche on a religion forum, because so many of your statements are right out of the atheist playbook. Either atheism or religion can be "faith based" in the sense of an entirely mindless adoption of a position for reasons having little or nothing to do with the ontological truth of that position. It is the atheist playbook that religion is entirely faith-based - i.e., nothing but delusional or "magical" thinking. In fact, serious believers - such as myself - have evaluated a vast body of scientific, anecdotal and testimonial evidence, as well as philosophical and theological arguments, in arriving at convictions that can be described as religious. The "leap of faith" in the direction of religion is not markedly different from the "leap of faith" toward atheism because the ontological truth of either position cannot be known in this lifetime. The comparison between a believer and unbeliever is simply a matter of how much diligence the individual has exercised in reaching his or her convictions and the depth of those convictions. Once one has reached a set of religious convictions and is inside the religious framework, then the term "faith" is indeed used in a slightly different and uniquely religious sense that is something along the lines of "internal knowledge."
At this point, the three-shot scenario is not unlike a religious conviction. The ontological truth will never be known. What you call "an overwhelming preponderance of the evidence" others who are equally informed do not find so overwhelming. I do not find it overwhelming. When no one can tell us when the first shot was even fired, and there is no physical evidence apart from a shell with an oddly shaped primer indentation and a dented lip, to refer to "overwhelming" evidence sounds very much like the claim of a religious zealot. You find the evidence sufficient to reach some level of conviction, while others find it sufficient to reach a different conviction or end up holding an "agnostic" position on the issue. That's just the reality - it's a matter of how one interprets the evidence.
Your persistence in calling Jack a troll is exactly what a religious zealot or militant atheist does. "Only I know God, and if you disagree with me and [my interpretation of] the Bible you're going to hell!" "If you persist in believing there is a deity, you're just a delusional magic thinker!" The number of shots fired by Oswald is an open issue as to which intelligent and diligent people can hold different views. There is no certainty and at this point can never be. Before reading Phantom Shot, I had never considered the possibility of only two shots. Having read it and looked into the issue more deeply myself, it is a theory that has a lot of merit. What further underscores that your position is akin to a religious one is that, ironically, the two-shot scenario doesn't challenge the LN narrative at all! It is only a threat to your "dogma." The Great Schism of 1054 AD that forever split the Eastern Orthodox Church from the Catholic Church was largely over the filioque - i.e., whether the Holy Spirit "proceeds" from only the Father or both the Father and the Son. It sounds completely goofy to me, but this "three shot or two shot" debate is strikingly similar: did three shots (orthodoxy!) or only two (heresy!) proceed from Oswald's rifle in the religion we call the LN narrative?
You make the assumption I am an atheist. If atheism could answer all my questions, I would probably be an atheist. It can't so I'm not. I am agnostic. Mankind has been pondering this question for as long as humans have had the ability to ponder. To the best of my knowledge, no one has come up with a provable answer. The late Dr. Carl Sagain, who was also an agnostic, said, "I don't want to believe. I want to know.". That pretty much sums up my position on religion.
As it applies to the JFKA, I KNOW that Oswald was the assassin. I BELIEVE he was acting on his own behalf but because I can't prove a negative, I can't logically say he had no accomplices. Only that I believe that to be highly unlikely. Ditto for the two shot scenario. There is ample, highly compelling evidence of three shots, both forensic and earwitness accounts. The WC recognized the theoretical possibility that Oswald could have started with an empty shell in the chamber and only fired two shots, but I find that to be highly unlikely.
