What I contend with is that she seems to be under the assumption that because of the Fall that mankind is absolutely perverse and literally incapable of doing anything good as a result, or if they do, they have some kind of nefarious or ulterior motive for doing it. Pure fiction and unscriptural.
Perhaps the problem is the term "total depravity?" That's a Calvinist term I may wrongly have assumed everyone here understands. It doesn't mean what you are saying above at all, but explaining it would get us deep into Calvinism which wouldn't be the place to go on this thread. I don't know where to go at this point, then.
