In the 70's and still in the 80's there were comedy-shows which people found extremely funny where white men imitated the way how black men speak.

If it wasn't for the guardian or bbc you would not be here either.....
If I moved to Japan or Korea, provided by that they allowed me to move there in the first place, and started to refer to myself as a new Japanese/Korean they would laugh their asses off. Even if I lived there for next 50 years to them I would be a foreigner.
