"Jim, you are a freestater, and as such have no conception of the North of Ireland."
Richie - your above sentence shows as little evidence that you were refering to an obscure (non existent) "derogatory term" as anything you have written so far shows the vaguest understanding of the present situation in Ireland - we can all make up excuses to cover our ignorance - you want to read some of Keithie's beauties!
Perthaps you might provide me with a reference of its use.
