We live in a world full of self centered people who will do evil things to people. It is ugly and should definitely not be tolerated. Parenting has challenges but never, ever is there and excuse for such behavior.
But how out of skew are we to call everything abuse. Parents are afraid to discipline they children the biblical way because they might be accused of abuse. Teachers have no real form of discipline in their classroom because of trepidation they may be accused of some form of it.
My own father could probably been charged with it if he lived today. But I never, even today, thought of it as abuse. His temper flared at my sister's mouth. But it was what he knew. What he grew up with. It wasn't often. It wasn't intentionally trying to hurt her. It was correction.
Experts today are finding all forms of abuse from physical, emotional, verbal and who knows what other labels they are putting on it. I do not argue that there are legitimate cases of such abuse. However, when a loving parent is accused of abuse by their child it is a death blow to the relationship. It can never be the same.
