Its true. Many white people still say that.
Weird thing is. When I was younger I did not hear white people say it so often.
But then again during that time I did not hear black people say it that often either.
What I'm typing here might be baseless and untrue,
but I started hearing the n-word more from both black and white people,
"most of the time with A instead of the hard R at the end", during the time it also started to come into popculture trough rap music and other means.
This might be completely baseless.
And would need some research, to know for sure.
It's still no excuse for anybody to say it though.
But that's just me.
