Well. It is well known that the Irish are portrayed in the Simpsons in a very stereotypical fashion. Normally as either drunks, leprechauns or both. Unfortunately, Ireland ceased to be a place resembling such ideas long ago and is now the second richest country in Europe (in terms of per capita GDP). I've learned to live with such scenes from the Simpsons over the years . Some were indeed funny (U2 being a prime example), but to be honest, I'm really tired of seeing them at this stage. The Simpsons Movie pretty much made up for all that went before it (Lisa's friend Seamus or whatever he was called), but I can see that things have returned to the way they are.
Not to say that the prejudices of the past are still evident. Indeed, the Irish assimilated into Amercan life much quicker than other nationalities. But the notion that the Irish in general are just a bunch of alcoholic wife-beating farmers is a load of nonsense. I know the Simpsons thrive on satire (more so in the past than today), but c'mon, they could at least treat every country with the same attitude. I feel that Ireland has been singled out one multiple occasions for no real reason other than a cheap laugh that serves no purpose. Hence the knocking of a whole point.
