Look up the definition of massacre, it certainly was in Tulsa.The POINT is that it was not a "massacre," and to characterize it as one is a lie. It was a "race riot" which turned out badly for the outnumbered and outgunned Blacks. Seems like the local Authorities could have handled it much better, but second-guessing from a hundred years later is rather lame.
There are no reparations for times when you get into a fight and lose. It was regrettable for a number of reasons but one must move on.
