What does it mean to be opposed to the promotion of multiculturalism by public bodies any way, if this is the objectionable policy?
I know a man from Mauritius, he is of the opinion that if you come to the UK you learn English, try to integrate, but you stil maintain your traditions, etc. in your own home. It is not clear what needs to be 'promoted' here.
My own family is of mixed culture. We maintain links with our other country by visits, cooking food, meeting people of the same national background, watching movies and other media of our other country, and so on. None of this is promoted by public bodies, yet we still are able to do it without promotion, eg with the support of the embassy. Obviously certain cultures enjoy a greater status in Britain, with translation services, and other public services, but it is from our experience not necessary, and to me it seems that you can oppose this 'public promotion' while still engaging in private activities that might be described as multicultural (and we do).
