Examples include the conflicts between Anglophone and Francophone Canadians, between Maori and Pakeha New Zealanders and between Anglophone White South Africans and Boers.
The term biculturalism was originally adopted in the Canadian context. Because biculturalism has the quality of suggesting, more or less explicitly, that only two cultures merit formal recognition, it has come to be seen as inadequately progressive when compared with the idea of multiculturalism (for which it formed a precedent).
In the context of deafness, the word biculturalism is used less controversially because the distinction (between spoken language and sign language) is commonly recognised as a genuine binary distinction transcending the distinctions between various spoken languages.
