I have had this conversation on the Escapist Team fortress 2 server a few times.
I was born in Cornwall,but moved to Dublin before I was 1 and have spent the rest of my live in Ireland.
Would I say I am Irish?
No,personally I don't think anyone,save a few communities in the far west of Ireland can claim to be Irish.I find that others on the the more eastern side of things have become more English.Some people are still bitter about the whole "700 years thing" but personally,I think its unfair to hold a grudge agaisnt anyone today just because of what their father's father's government might of done,but in fairness,although some of the Irish culture is still there,I personally feel we have become largely English.
I mean no offence to anyone,and might I also add if someone wanted to be Irish,anyone could be,nothing stops anyones from using Irish commonly,playing tradition music and such.
I also don't mean to say you must do EVERYTHING possible to be Irish(by which I mean talking Irish CONSTANTLY,listening ONLY to tradition Irish music etc) I just think alot of Irish life has,along with the country's technology,ecomony and just about everything esle,I feel its grown as close to England as possible-and thus,lost alot of its modern cultural development,because they were so vital to becoming modern.
At this stage I may have lost myself abit so I'll leave it that.
