You put forward a considered proportionate viewpoint, so I've changed the title, reluctantly.
But I don't think it is derogatory to the Irish, when I used to visit my relatives and catch the ferry to and from Holyhead we all used to call the boat that name all the time.
The right to offend...
No, but as my dad is from Tipp, my mum lives in Mayo, my sister is in Dublin, and I have an Irish passport, perhaps there's a little bit of irony in the thread title?
