Xenophobia, from the Greek ξένος (xénos, foreign) + φόβος (phobos, fear) is a fear of that which is inherently other. Xenophobia is inherent in human history and human nature to some degree. Examples of xenophobia are evident in common American culture, such as the fear of the influx of Mexican culture in the border states or of Russian hackers and nukes.
Technically, xenophobia is not racism; xenophobia refers to a fear or dislike of different or foreign cultures and beliefs that are generally unknown to the phobic person while racism is the feeling of superiority to a specific race.
