If you read my post, Madame President and Mr. President is/would be both, politically correct and protocol. Latter suggests the second, not the first.
Me: As ex-Presidents are always acknowledged as Mr. President, I assume it would Mr. and Madame Presidents, William and Hilary Clinton ,or vice verse. Maybe due to the fact she would be a "setting" President, Madame and Mr. Presidents Hilary and William Clinton. It should prove interesting, though I think the latter would be politically correct.
You: Not politically correct. Just correct protocol. The current president takes precedence over his/her consort and over past presidents
Me: It can be politically correct as well as protocol, vice verse would be against protocol, as well as politically incorrect.
You: I have never understood the concept of political correctness. It is too vague and elastic a term for this mathematician to grasp.
IMO it varies according to the mind of the observer. Who/what is the arbiter of political correctness? Where can I find definitive guidance?
Me:
Political correctness (adjectivally:
politically correct), commonly abbreviated to
PC,[SUP]
[1][/SUP] is a term which, in modern usage, is used to describe language, policies, or measures which are intended not to offend or disadvantage any particular group of people in society. In the media, the term is generally used as a
pejorative, implying that these policies are excessive.
