Step-by-step explanation:
The irrational fear or hatred of people from other countries or cultures is known as xenophobia. This term describes a phobia where individuals experience anxiety, discomfort, or unreasonable fear when encountering foreigners or foreign environments. It is often associated with feelings of unease towards those perceived as 'different' due to their cultural, racial, or ethnic backgrounds. Cases of xenophobia can range from mild discomfort to severe panic and avoidance behaviors.
Xenophobia is one type of anxiety disorder which may impact individuals socially and emotionally, and it is crucial to distinguish these serious conditions from common, everyday worries. Other anxiety disorders include obsessive-compulsive disorder (OCD), panic disorders, posttraumatic stress disorder (PTSD), and specific phobias such as arachnophobia (fear of spiders), claustrophobia (fear of confined spaces), and agoraphobia (fear of open or crowded spaces).
