So, the Irish owned bookmaker firm Paddypower is strange form of self-hatred? As it happens personally I don't tend to call people either Irish people or people from Pakistan by 'slang' generic names reflecting certain nationalities either as individuals or collectively, but 'Paddy' feels different to 'Paki' to me for whatever reasons, and I think it's largely intent as many posters have suggested. However, I'm sure Irish people in the UK have had the word Paddy used unpleasantly against them or even patronisingly, which I assume is just as bad. But I don't know. On the other hand I'm happy using Scouse/Geordie, Cockney, Mancs, ect and also happy using Taffs and Jocks (Sweatys) and Yanks, Aussies, safas and Kiwis as collective terms - almost always used in terms of sport although not to individuals. I don't mind being called a Pommie or a Brit, although the latter is sometimes used with 'intent', but then historically we Brits have tended to be oppressor rather than the oprressed..I dunno, go and figure but it doesn't feel the same to me, 'Paki' is now and probably always was racist.
