Bullying has been institutionalized for many years by religious groups.
Children are regularly abused psychologically and physically for their
"rebellious" questioning of their parent's insanity.

"Spare the rod and spoil the child" is not in the Bible but from Dr. Johnson.
Still it is used as a device for bible reference by parents to bully children.

Children learn to be abused by their parents, siblings, teachers, and other authority figures. Do you wonder why it is so rampant?

BTW what happens when one nation bullies another? Does this trickle down?
