My parents had trouble in Dublin during the 70s and my mum had a skinhead poor beer over her when she was pregnant with me (early 80s) but nothing in the last 10 years or so. Aside from some problems with some neighbours, but they were just generally awful and trashy rather than racist.
My sister had someone say something to her in the pub about five years ago, along the lines of her being a mail order bride and she had to stop her husband from seriously laying into the bloke. (Which would have been quite funny as he's quite a middle class guardian reader) and my brother has had no problems relationship wise but did once get a bottle thrown at him from a car and was called an offensive C word. I think he chased the car down the street shouting "I'm not even Chinese you W...."
We used to get the whole "Is one of you adopted?" thing a lot when we were younger.
I am the (white) sheep of the family and look 100% caucasian (genetics are strange) so don't feel I can really comment on it, but from listening to my parents, it seems that Ireland was worse than England (in the 60s/70s at least!) and that it's mostly died out now. My brother and sister don't really get any hassle and I don't think my nieces realise what racism is yet.
My mum does get people ranting about immigrants to her at work but then they realise she's an immigrant and say "oh not like you. I mean XYZ" Mostly she just smiles quietly and secretly puts a black cross against their name in her head!
