From the Greek words ξένος (xénos, foreign) + φόβος (phobos, fear) + -ia.
An exaggerated or abnormal fear of strangers or foreigners.
A strong antipathy or aversion to strangers or foreigners.
From the Greek words oikos meaning a “house,” “family,” “people,” or “nation” and phobos.
An abnormal fear of the home, or of a house.
Recently expanded to mean an extreme or irrational fear or dislike for one's own people, home, nation and culture.
So you know; there is a strong liklihood that anyone you encounter making accusations of Xenophobia is simply suffering from Oikophobia.
