xenophobia
Prejudice, fear or hatred of outsiders. Although called a “phobia,” this is not actually a medical or psychiatric diagnosis. Rather, xenophobia is a sociological issue. It can overlap with racism or other forms of hatred and oppression. It can be implicit or explicit, and can be expressed in personal, systemic, economic, violent, and rhetorical ways.
Xenophobia is often thought of as a dislike or fear of immigrants, but it can also be a fear or dislike of someone from a different community or culture (often termed “cultural xenophobia”).
