There's absolutely no point trying to reason with the nutters. I have never seen any indication of a willingness to study all the evidence which makes discussions extremely one-sided and endlessly frustrating. It's much like trying to reason with a cult member. But I would debate anyone at any time in any forum that was open-minded and reasonable. There are so many reasons to exonerate Oswald, where would I start? First, ask yourself a few basic questions: Why would Oswald purchase a gun by mail order when he could have acquired a much better gun without any paper trail? What competent assassin would select the "humanitarian rifle"? What happened to the Mauser found in the Depository? Wouldn't that be a much more accurate weapon for an assassination?
What about the bone-headed SBT? Does anyone with three active brain cells believe that nonsense? Let me help you: count the witnesses at the autopsy who reported that the back wound went in "less than a finger's length" and did not exit the president's body. If their testimony is correct, the SBT is annihilated. Why should I believe Sibert and O'Neil? Why should we believe the exact same testimony from mortician Tom Robinson? I'm sure someone will try to discredit these witnesses, but what they reported was very important. Hoover, one of the most evil individuals in American history, was too ignorant to know what his own agents really reported concerning the autopsy.
But I will be attacked by the trolls who are unable to answer even the most basic question without prevaricating...
