Oikophobia
Oikophobia (Ancient Greek: οἶκος, romanized: oîkos, lit. 'house, household' + φόβος, phóbos, 'fear'; related to domatophobia and ecophobia) is a tendency to criticise or reject one's own home or home society while praising others. It has been used in political contexts to refer critically to political ideologies that are held to repudiate one's own culture.
