I am not aware of one particular word that meets the definition you've suggested. However, there are a number of words (often compounds) that express thoughts about a specific culture or religion. In many cases, these words combine an ethnic, national, or religious term with a compound such as anti-, -philia, or -phobia.
- Germanophobia: strong dislike of, or prejudice against, Germans.
- Italiophilia: love of or favoritism towards Italy, Italians, and Italian culture.
- Antisemitism: hatred of Jews, Judaism, and Jewish culture.
- Papist: a derogatory euphemism (of Protestant origin) for a Roman Catholic.
- Anglocentrism: a tendency to regard English culture, society, or language as pre-eminent.
- Japanophile: One who loves Japanese culture, history, language, etc.
- Semitophilia/Judeophilia: the opposite of antisemitism.
- Anti-Protestantism: disdain for Protestantism.
Note that the first six words exist in the OED, whereas the remainder do not.
