Still, i see nothing speaking against renaming an unimportant geographic location as to not have it include a word anymore, that is nowadays still used in mostly condescending ways.
If you openly refer to a person as 'Neger' in public (as in, "well, i'm lost, maybe we should ask the Neger over there for the way to the train station") you'll earn some weird looks. It's a word that has been mostly removed from everyday use.
It's difficult because Europe doesn't have that big of a history with African minorities. In Austria, the "Nigger" situation would be most compareable to the word "Tschusch", which is:
* throughout the late 1900s used as a
slur against immigrants from slavic / south-east-european / oriental countries
* nowadays frowned upon but still used by people who are rather backwards (in the 'negro' kind of way)
but ALSO
* embraced by young people of said ethnic group to refer to one another
But who am i to judge, i still regularly have a "
negro in a shirt" as dessert.
