It's interesting as PeteZ pointed out, the connection between the time that has passed since the perception of wrongdoing and the reinstitution of the statues for historical reasons.
The pyramids were built on the backs of slaves. Shall they be razed to the ground?
I read an interesting article about the statues controversy a while back and I cannot find the article now. In it, the writer made two points.
One was the number of tourism dollars that are negatively impacted (the author used the city of New Orleans as an example) and the volume of people who like to stroll browse and read what is on the statues - which are works of art regardless of if you like who it is depicting. The article pointed out that in countries where art and statues were removed for sensitivity reasons - tourism dropped - the cities just weren't viewed as being steeped in culture and visually as interesting. In most cases, the statues were restored.
Two was an in-depth look at what Scandanavian countries faced when the split over Viking history was a hot issue. "Viking Day" or not? Museums or not, statues or not? The end decision was to keep the Viking heritage simply as history. NOT as a venerated part of history but merely as history.
And isnt that the point? The BLM movement should be very quick to want to teach people to do better in the future. Doing better means knowing better. The way society collectively learns to do better is called history. To sanitize the history associated with the Civil War is a two-edged sword. Yes, you remove painful reminders, but you also remove the reference points that made it living and real to future generations to learn from.
White children will not have any concept of what the big deal is. Black children will hear "words" but they won't have any frame of reference to aid them to internalize the sacrifice that was involved. For all of these children of the future- its just words at that point.
Once people are acting on principle again and not just acting out using raw emotion as fuel, once they are using their heads......
I guess that is when Christopher Columbus statue in Boston can have its head put back on again.
