Xenophobia

Xenophobia is the fear or dislike of people who are perceived as being foreign or strange. It is an expression that is based on the perception that a conflict exists between an in-group and an out-group and it may manifest itself in suspicion of one group's activities by members of the other group, a desire to eliminate the presence of the group that is the target of suspicion, and fear of losing a national, ethnic, or racial identity.
