You will note also that the battle of the Boyne was 327 years ago and the Ulster Unionists still have their "marching SEASON" when the have march after march celebrating victory over Catholics. In early July each year it is so obnoxious that some citizens of Northern Ireland flee south across the border temporarily to get away from it. I happened to have a holiday booked in Donegal around that time, and my accommodations had a water problem: talk about a tough challenge to find an alternative place. So by all means Sein Fein should try to forget some things, but it could be made easier.
