'jestem polakiem'
There is no other way of saying "I am Polish" in Polish (unless of course one is a female) - it's not quite like saying "niggas" or "niggers" if one is Afro-American.
RUBBISH to your comments. I disagree.
Well, you're quite free to say and think anything you like - nonetheless being called "a Pole" is simply not an insult.
it depends on the intonation
Exactly! But in this case - if the intonation is aggressive (for example, as when words are written in capital letters, where the aggression is implied) even "Polish"
couldbecome an insult.
