The conventional arguments made in the Republic against a United Ireland are the inconvenience of integrating one million Protestants into Irish national institutions and the cost of maintaining British levels of subsidies to the Northern economy. But, it could also be argued, that 90 years of separation have created equally profound differences between Catholics North and South of the border, similar to the Ossi-Wessi gulf that persists in Germany. On the national question, Northerners have accused "Free Staters" of being "soft" since independence, being accused in turn of being obdurate hardliners. The drift in the Republic towards secular liberalism hasn't been matched in the Six Counties, where a greater degree of Catholic conservatism pervades both nationalist parties. These trends are particularly apparent in Ulster GAA, with clubs named after and commemorating hunger strikers, which the national organisation rightly steers well clear of, and also in opposition to rule changes. There are probably others that are more apparent, but unification would take decades to erase this gulf.
