The article you linked winds up obsfucating the facts in its attempts to be sensitive. The "n-word" on the headstones that people take exception to is nigger
, not negro:
"EL DORADO HILLS, Calif. – Time has weathered the 36 concrete gravestones in a dusty, half-century-old cemetery tucked away in a corner of California's former gold fields. Time has not erased, however, the bigotry of a bygone era carved into the markers. Source
The dead, both black and white, had been moved from a Gold Rush-era hamlet known as Negro Hill in the 1950s to make way for a reservoir.
The problem is the way the markers continue to identify them almost 60 years later:
"Unknown. Moved from Nigger Hill Cemetery by U.S. Government - 1954."
A group of white people, led by a Boy Scout doing his Eagle Scout project, wanted the name changed back to Negro Hill. At this point the African-American community (quite rightly) said, "Hey, don't you want to know our opinion on all this?"
Given that racist place-names ("Squaw's Tit", "Savage Island", "Nigger Hill"…a monicker that the Army Corps of Engineers imposed on the region in the 50s pretty much solely because they were a bunch of bigots) are active reminders of institutionalized bigotry and discrimination in the past, taking steps to sensitively deal with them seems to make quite a bit of sense, and has nothing to do with bowdlerizing separate and unrelated works.
