Right because neither the OP nor the parent comment gave any hint they had been abused. There's no question that abuse is harmful.
One of the tenets of "positive discipline" is that disagreement and rebellion are expected. By accepting such behavior, a trained therapist may earn a child's trust. And, that can be helpful to a school or therapist to discover if abuse is occurring.
That said, if you know a kid hasn't experienced abuse, you might wonder whether or not they receive any attention for doing good things. They may be acting out more because that's what got them attention. What constitutes "acting out" is very personal for each family and individual.
