It's easy (I know, because I've done it) to lob "common sense" LN sound bites at CTers because of their love of fantastically complex JFKA and cover-up scenarios. The CT community is its own worst enemy in this regard. That's why my threshold question is always "Does that make any real-world sense at all?" Often, the answer is no.
But there are CT scenarios that the LN sound bites really don't fit. They aren't ridiculously implausible. They don't violate common sense. If the CT community would focus on these and the most problematical aspects of the LN narrative, it would do itself and serious research a big favor. Alas, it seems that many CTers just can't help themselves.
Likewise, it's easy to lob CT sound bites at those who think the JFKA starts and ends with the WC and Bugliosi. EVEN IF THE LN NARRATIVE IS CORRECT, the WC was a badly flawed, agenda-driven "investigation" that is almost entirely responsible for what has transpired ever since. For multiple reasons, it was nothing like an objective, fact-finding investigation. If I were a LN advocate who wanted to be taken seriously, I would banish the WC and Bugliosi from my vocabulary. Alas, it seems that many LNers just can't help themselves.
It is just astonishing how closely JFKA discussions parallel religious debates. They never go anywhere either, for precisely the same reasons. The fundamentalists, heretics. cultists and atheists just talk past each other.
Though both sides of a religious discussion will point to evidence, it largely comes down to a matter of faith which is why I never argue about religion with anyone. Whatever someone else wants to believe, if they are content with it, who am I to tell them they are wrong.
The JFKA has a wealth of evidence which needs to be looked at objectively. When I see people who start with a preconceived conclusion and then dismiss or accept the evidence based on whether the evidence fits their chosen conclusion, I have no problem telling those people they are wrong.
