You are now being more clear...thank you.
The P word is widely used as a term of abuse....please see the attached youtube link. The dreaded P word is the first thing that is heard. I am sure that you or anyone else is not condoning this sort of ignorant, racist behaviour.
Coloured is also seen as a term that was used in past times, when non-white people were widely discriminated against. Anyway, the term "coloured" is meaningless....I don't know any green, blue or purple people.
If these are the only examples that you can think of, then I would have to say that I disagree with your original post.
