Question

Many people believe that if you aren't physically harmed violence dose not affect them why or why not

Answer 1

Physical violence can have a negative impact on someone even if they aren’t physically affected by it. For instance, a child suffers emotional issues from witnessing parents fighting. Another example is that people are affected by community violence, even if they aren’t personally involved- it can cause stress and anxiety just the same.
One more example would be the emotional impact of war/combat on civilians and other.
