Thanks for the posting. I know exactly what the author is saying since I had a similar experience at Philipsburg Manor in Westchester County, NY. For years the tour of the Manor house and grounds focused on the life of absentee Dutch landlords and their huge Hudson River Valley farms. However, within the last few years, the emphasis has shifted to slavery. That is all the docents talk about! The Philipse family is presented as an afterthought and the slaves are the main event. While it would be poor history to ignore the slave labor that worked these NYS farms in the late 17th century to early 18th, it is revisionist history to discard the Europeans whose efforts established our country.
When Philly wanted to improve their Liberty Bell display, the black groups insisted that there be a big slavery presence. It was like they wanted to co-opt the Liberty Bell monument. I wouldn’t mind if somewhere a group of African Americans bought some land and created a museum or monument to ‘Slavery in America’, just stop trying to shove it into everything else.
