Polyethnic groups are less deserving of such rights since they come to the state voluntarily and thus have some degree of responsibility to integrate to the norms of their new nation. This does not mean that they are not entitled to any rights as Kymlicka argues that all cultural minorities have a right to choose their own lives, but it does mean that they are not entitled to the same level of group rights which minority nations would be entitled to. Kymlicka makes various exceptions such as the problems faced by refugees, whether from conflict or poverty, and by such minority groups such as African-Americans (whose heritage in America clearly did not begin voluntarily) and argues that their needs with regards to cultural group-specific rights should be considered on a special basis.
