Who is considered a xenophobe?

The term "xenophobe" describes an individual who exhibits an irrational or excessive fear and aversion to what is foreign, particularly concerning people from other countries or cultures. This fear may manifest as hostility, distrust, or prejudice towards those perceived as outsiders. Thus, the correct answer captures the essence of xenophobia, which is inherently linked to fear and discomfort with the unfamiliar.

In contrast to the other options, those characterized by admiration of foreign cultures, promoting diversity, or seeking to understand different cultures display openness and appreciation for diversity rather than fear. These behaviors are antithetical to xenophobia, which is rooted in a negative perception of foreignness. Therefore, understanding the definition of xenophobia clearly leads to identifying the correct choice as someone who is unduly fearful of what is foreign.
