I guess doctor Lamb got her PhD in retarded theory with that paper. Long story short 99 percent of the fiction characters are not suitable for role models (Kain and Abel, Don Quixote, Optimus Prime, etc.) Best role models come from real people, that is where parents should point when trying to teach their children role models.
It would be great to take Iron Man as role model, specially the get rich and do fun stuff, but even with the limitless powers of the internets i don't really think that many children can get that rich really fast.
Anyways if she is so desperate to protect the children i would suggest her to leave comic super heroes alone and start to look at bigger threats to them like real weapons manufacturers, drugs, retarded psychologists.
