In at least 20 years and likely much longer, I haven't heard a single white person utter the "n" word. (Quentin Tarantino movies excepted.)
However, I hear black people using it all the time, especially in the stupid rap songs they sing.
As for swastikas and KKK, give me a break. There's something like three people in the KKK these days and nobody writes swastikas anymore, except when somebody wants to plant evidence in order to fake a hate crime.
And all three of them are FBI informants.
