The definition that I have always relied upon is that Child Sexual Abuse is ANY activity involving a child for the purpose of adult sexual gratification. This activity permeates all economic and social strata. It takes place in housing projects and in mansions. It takes place in church congregations and in pagan and occult communities. Child Sexual Abuse knows no sex, race, religion, nationality, lifestyle, etc.
Every child is at risk.
If you suspect that a child is being or has been abused, it is your responsibility to report that suspicion regardless of your relationship, or lack thereof, to the child. In some states it is a crime to suspect abuse and not report it. The answer to this question generally surprises people. They can be a friend, a neighbor, a child caregiver, a teacher, a religious leader, a community leader, a co-worker or even a family member. In fact, quite the opposite is true.
