2/ The alternative to multiculturalism is Integration. – Joanna Fomina

3/ Integration has outlived its usefulness; a multicultural society ought to be the goal. – Sarah W. Oelberg

4/ “Assimilation, American Style” implies that immigrants are free to retain or discard as much or as little of their homeland cultures as they wish without compromising their assimilation. Assimilation does NOT mean that immigrants must give up their ethnic culture; to think so is to confuse assimilation with acculturation.
The three most crucial institutions of assimilation – the English language, liberal democratic capitalism, and the Protestant work ethic – is absolutely necessary to the success of any new immigrant group. – Peter Salins

5/ America is desegregating. What television has done is to give white Americans the sensation of having meaningful, repeated contact with blacks without actually having it. We call this phenomenon virtual integration. – Leonard Steinhorn and Barbara Diggs-Brown

6/ Upholding integration must mean a clean break with multiculturalism. It would mean teaching British culture and values in schools; it would mean refusing to alter this country’s fundamental laws and traditions to accommodate special pleading by minorities. – Melanie Phillips

7/ Integration includes goals such as leveling barriers to association, creating equal opportunity and the development of a culture that draws on diverse traditions, rather than merely bringing a racial minority into the majority culture. – Wikipedia

8/ a) Pluralistic multiculturalism views each culture or subculture in a society as contributing unique and valuable cultural aspects to the whole culture. b)Particularist multiculturalism is more concerned with preserving the distinctions between cultures.- Diane Ravitch

9/ Multiculturalism means different things to different people. If I had to identify a common ground that unites all self-proclaimed multiculturalists, it would come down to two points. First, all cultures are equal in value and have an equal right to flourish free from external constraints; and second, the greater good of humanity – defined in terms of peace, love and understanding – is best served by people living within or directly experiencing as many different cultures. The irony or contradiction within this ideal of diversity lies in the historical reality that all of the traditional cultures celebrated in the multiculturalist literature were able to flourish and develop their unique beauty precisely because of a degree of isolation now judged to be the incubator of intolerance. – Christopher Shannon

10/ The term multicultural means the general things to do with cultural diversity such as cuisine, dress, and media, that might add to a quality and diversity of life. Such a diverse society [for which Rob Imre prefers the term Integralist multiculturalism], means that there is an acceptance of things multicultural and a great skepticism and even rejection of multiculturalism.
The term multiculturalism than, is an ideological position that advocates a particular set of policies that actively promotes this diversity and support the preservation and development of migrant/ethnic groups and cultures. – C.W. Watson

11/ Multiculturalism is a slippery ideology, in that there is a myriad of variations to the concept. This wealth of definitions is actually a great advantage to the supporters of multiculturalism, as it is easy for them to deflect any attacks upon their viewpoint, by saying “Oh no, that’s not the kind of multiculturalism that I’m talking about”; they can swap, merge, and confuse definitions, and therefore dodge valid arguments by avoiding “being pinned down” to one definition.- Cameron McKenzie

12/There is a difference between Soft Multiculturalism – the idea that minorities should not face discrimination and that the customs of different people should be tolerated, and which he describes as a ‘benign force’ – and Hard Multiculturalism, which insists no culture is better than another, and which believes society should not only tolerate difference but promote it. – Patrick West

CONCLUSION: Multiculturalism is a term that has never had a stable meaning. It has been both attacked and stalwartly defended by critics at all points on the political spectrum.
