@Lustig Andrei,
If it is, then I won't use it.
They do, though have a hockey team the Vancouver
Canuks.
It seems if Canuk was offensive they would have changed the name.
We don't have The Seattle Seppos.
We do have the Washington Redskins (which I think should be changed), but it refers to only a small group that has no real political power, not all Americans.
