The less offensive term of equal clarity and brevity is British  Irish Isles Believe when I say that the Manx natives have no trouble with this description as they are linked to the UK as a protected and supported territory Republic of Ireland on the other hand is a sovereign nation with no link to the UK  The basis for usage of the term is completely flawed logic as it refers to ancient texts etc and precedent for calling them the British isles Place names reflect current realities thus we have Istanbul and not Constantinople  A better example would be the Aegean coast of Turkey and its islands this whole area was once referred to as the Greek coast and all the islands were Greek islands since the political landscape has changed and the Turkish state has jurisdiction the only islands which are now Greek islands are those within the jurisdiction of Greece if you were to rebut by saying that British refers to something more than a political term but rather than an ethnic or geographical one then the same argument or even a better one can be made of Greek the Greek world once referred to an area far greater than modern or ancient Greece eg southern Italy Sicily turkey Armenia etc and many of the people residing in those parts of turkey which were formerly designated Greek are ethnically and linguistically Greek but live in the state of turkey and therefore the islands and coast are Turkish  Thus you could not refer to the island of Ireland as British
