This chapter describes some prevalent ideologies and attitudes found in minority language communities. It emphasizes the importance of listening to attitudes expressed in a community, and identifying the underlying ideologies, before developing programs to improve negative attitudes. Particularly in cases of linguistic discrimination and language trauma (e.g. Breton, Kashubian Polish), changing language ideologies is a long-term process and must be handled sensitively. The best approach is to make people aware of ideologies and how they function, through education, media and other means. Case studies address ideologies leading to the loss of Zadar Arbanasi in Croatia, and a positive shift in attitudes to Guernesiais, although these are not necessarily followed by action. In the Isle of Man, in order to change perceptions of Manx it is necessary to avoid arguments about the authenticity of the modern form of the language. In Jeju (Korea) Jejudommal is seen as a language in which emotions can be expressed more richly than in Standard Korean. Negative attitudes and ideologies associated with speaking Nahuatl are described.
