Never heard of the term before this thread. Because it has been juxtaposed with the term "political correctness" in one of the questions, I infer that it may be proposed as a more positive alternative to the term "political correctness". If so, while I think that's a nice thought, since it infers the opposite of itself (multicultural incompetence), it won't be taken as positive by those who currently use the term, "political correctness", and its use will be preaching to the choir.
