Approximately 100%, in my opinion.

Of course, trauma can be many things -- not necessarily "abuse" by parents or others. That does seem to be the most common form. "Trauma" means a stress that is not overcome by the person's defenses or resources, so that it depends on an individual's makeup and experiences too, as well as the help the person can get.

What do you mean by "tougher stand"? Punishment? Will that get us anywhere except more of the same? If by tougher you mean being more forceful in marshalling resources and knowledge to help a person, then I agree with you.

I do not expect to make the top of the popularity poll by saying these things.
