Warm black dingus story was BS
Ok first of all we know that major warren has no credability. His Lincoln letter was a forgery and he lied about that sign that prohibited Mexicans. I think that warren just made up that story to anger the general into pulling his gun on him. That way killing the general would be self defense and not murder. I know the scenario warren described was plausible but what were the chances of Chester Smithers and warren actually coming across each other and why would Chester be stupid enough to tell warren that he was the son of the infamous confederate general? And the flashbacks were probably general Smithers just "seeing pictures" of what warren was describing.
If this had really happened it would not be funny because this was rape which is no laughing matter. But what better way to piss off a racist former confederate general than saying his son was killed by a black man after performing oral sex on him? Like in Pulp Fiction with the glowing brief case Tarantino leaves it up to the imagination to determine if this really happened or if it was just a cooked up story as part of a plan to kill a racist confederate general. The odds of warren and Smithers actually meeting in Wyoming were slim to none and it might have been that right when warren saw he was there he was thinking of a good excuse to kill him.
