In Hong Kong there are many of us who want to preserve Hong Kong/Cantonese culture from erosion by CCP/mainland culture. For example, sometimes you can see a lot of mandarin around school kids rather than cantonese. The government is also pushing for schools to teach in mandarin rather than cantonese. Mandarin is the language for mainland china, Cantonese is a minority language.
I imagine it is like this in other parts of the world where someone from a ‘minority’ culture wishes to preserve their culture & language against the dominant culture/language. Is there a word for someone like this in English?
the closest i could think of is “nationalist” but that’s definitely not correct, it’s not like one saying one culture is superior, but just that you want to protect it and conserve it and keep it in place.
most of the terms around identity politics have regrettable connotations :/
i guess conservation is the closest to what op is asking for.
Brittany in France, Catalonia in Spain, Flanders in Belgium, Basque?
Not independentist or separatist but rather protectionist
Preservationism has already been mentioned. Or “heterogenous” culture (also often called multiculturalism, but the latter term also have a lot of history which might not apply)
