From Project No-Spank

""Any form of corporal  punishment or `spanking' is a violent attack upon another human being's integrity. The   effect remains with the victim forever and becomes an unforgiving part of his or her
personality - a massive frustration resulting in hostility which will seek expression in later
life in violent acts towards others. The sooner we understand that love and gentleness
are the only kinds of called-for behavior towards children, the better. The child,
especially, learns to become the kind of human being that he or she has experienced.
This should be fully understood by all caregivers." -Ashley Montagu (Anthropologist)
