How do people get xenophobia?
This really cannot be answered broadly. It would vary from
person to person, but with some introspect the answer can be found.
The person would have to look back into past, and try to figure out
what set it off. This is like any other phobia, there are people
phobic of feet-podiaphobia, one cannot say all people that are
phobic of feet is because of fear of germs, it is an individual
answer.
