Declan,
It would appear from your use of PC and the song beng "one of your least favourite" having been forced upon you in school, that you talk of "The Mainland" when you mean England, a "Post nationalist Ireland" when you mean an Ireland which denies its identity ( a good thing in your reckoning). What's your next step? Re-absorbtion into the British Commonwealth of Nations with Queen Elizabeth ll as your liege? The abolition of Hurling and its replacement with The Marylebone Cricket Club? A similar fate for Gaelic Football at the hands of Rugby? - Soccer would be too vulgar for you. The handing over of Croke Park to anyone who wants to use it provided its use is in no way "Irish"?
The realisation of your dream could be nearer than you think !!
