The post Tec3009 made which was deemed to be offensives actually was stating definitions of the slang words used to describe people of different ethnicity.
The definition of Red neck and Onki was also included.
Since when has a definition of a slang word been deemed Racist?
And I defy anybody to try and stop people using the language they choose.
As Tec3009 stated, it is not necessarily the word which is offensive, but it is the context in which the word is used which can be offensive.
For example, if one African American greets another African American on the streets of Detroit and says "Hi Nigger", then this clearly is not a racist remark as the guys are greeting each other in a friendly and sarcastic way (their way).
However, if an African American went into a shop and the shop keeper said "Hi Nigger", it would be totally inappropriate and regarded as both racist and hostile.

So to ban somebody for giving definitions of slang terms used by the Prince and others for both white people and those none white people is clearly political correctness gone too far.
