Any Irish accent is a fine accent (I'm not Irish btw!), and fankly, does it matter?
I don't think you get it. It matters when you're in the UK and apparently your accent codes for a small but significant minority of British people as 'uneducated, superstitious, probably alcohol-dependent Paddy Thicko', and this minority is more than happy to share this hilarity with you. Not once, but frequently, and the depressing thing is that it was never possible to predict who was going to come out with this stuff, from a random man at a bus shelter in the Midlands to a neighbour at an Oxford High Table.
And no, I (obviously) wasn't looking for the friendship of any of these people, but I was expecting not to be subjected to mockery on the grounds of my nationality, or discriminated against because of it. Why don't you 'change accent to skin colour' and see whether that gives you a greater insight?
