There is no "dilemma," except in your mind. I am speaking directly to the habit of some people to omit crucial facts in their presentations deliberately, which is dishonest.
Which is exactly what the left wing censors who want to remove southern symbols do when they defend Robert Byrd.
You have the shoe entirely on the wrong foot.
Nonsense. What you say are "southern symbols" (and really white-supremacy symbols if you are honest) are just being moved from places of prominence in public space, as they represent different things to different people, often times negative, and a place of prominence in the public square symbolizes universal public acceptance of these symbols as something good. These symbols belong in museums where people can go to see them and study history. Aren't there museums in the south? The history of white southerners up to and through the Civil War is widely known. It's studied in junior high school.
But anyway, we are discussing one single individual and how he is being described to the public. His history is known, but why is it being edited down to omit an important part of his life?
