Has the GAA made Ireland Less United?

Does anyone else feel the GAA have made Ireland less united? Which of course defeats one of their original (unstated) purposes. Because of Republican factions (Tyrone particularly opposed Adams constitutional shift in the eighties) Tyrone already feel estranged from "nationalist leaders". And its hard to imagine Kerry people would have the same sense of separateness and parochial identity withoutthe help of one of Irelands most enduring, secretive and changeless organisations (the GAA). Actually I will have a wager, with the rise of popularity in Munster rugby and the recession inevitably going to hit rural Ireland disproprotinatly, I will witness the rise of "Munster nationalism" in my lifetime. For goodness sake people, the boys from Co. Tyrone are your brothers.
