Middle school and high school teens are the target in most cases. Not understanding there sexual urges developing and wanting to gain acceptance it is part of the peer pressure that exists today.
Taking prayer out of public schools has caused a massive weakness in society today. A steady decline in public schools can be shown to go as far back as the 1960s.
