I think you will find that removing the best and fairest award from the 1930s awarded to Dyer, is the opposite in the status quo.
The upside is having an accurate representation of history and not one fudged by reputation
That's my point, they prove Dyer really was B&F, status quo maintained, nobody any the wiser.
Alternatively, if there is doubt, it doesn't improve anything, nobody has a greater understanding or appreciation of Richmond's history. All they achieve is upsetting the people for whom the legend means something.
I could provide forensic evidence to my dear old 83 year old mother that Christ never really existed, or didn't really turn water into wine or whatever, and prove to her everything she has held dear her entirely life is a lie. It might be the accurate representation of history, but it also kind a dick move that leaves neither of us better off.
