And is some folk self describe themselves as plastic Paddies, who is being offended? The meaning is quite clear, someone who adopts a commercialised irish personna ( like waiters, barmaids and entertainers in Irish theme pubs). If it is lucrative, the perpetrator is honest, and actually entertains audiences who freely go to be entertained, knowing that the musician is about as Irish as yorkshire pudding, what kind of puritan prodnose would wish to be 'offeneded'.
