Kman543210, I agree with your first two comments about violating NPOV, and I did not persist further.  If you read the blocking guidelines, it is to prevent FUTURE issues and not punish previous behavior.  Your view on Nigger being derogatory and offensive is a violation of NPOV.  Nigger is a term used to describe African People, and your view of it being derogatory or offensive is an opinion that violates NPOV and is thus irrelevant.  I suggest you read the blocking and NPOV guidelines.
