Well, that is why I added "not linguistically or nationally", because in America at least it is used as a racial slur against Polish Americans (who mostly have no/negligible knowledge of the Polish language). Obviously it isn't offensive in Poland, you think I don't know thatOne of the odd ones.. Seeing as Polak is Pole in Polish.

See above.Calling a Pole a Polak is like a Spanish person calling an Englishman English instead of Ingles. It really out to be less offensive. (Well, calling a Polish woman a Polak instead of a Polka could be offensive, but no more than referring to Latino women.)
See, Arwon, that's the proof that there is such thing as "political correctness". R-Word? I mean, really? What are we, stone age bushmen afraid of saying some words out loud because it might anger some vindictive god?
It's the same with "n-word" and other crap like that. The words on themselves are not offensive. They can be used to offend, sure. But you don't need them to offend anyone.
Censoring words does not destroy our ability to offend. I understand the orwellian purpose behind such practices, but it does not work like that.
Yes, censoring doesn't lessen our offensiveness, it simply lessens our resistance to potentially offensive stimuli. We should try to be respectful to each other, and avoid unnecessary provocations, but we should not shy away from the challenge of letting go of anger or frustration regarding slurs. Why must we live in a plush, fur coated existence?
