[sarcasm]Yeah, there's the hallmark of objective research for ya! Forrmulate a premise based on your own preconceived notions, then dismiss as irrelevant every piece of data that makes hash of your theory. And while we're at it, just limit your field of research to one small area the requires the least amount of data-digging so you don't run the risk of having your cherished paradigms challenged.[/sarcasm]
The creationists and 9/11 conspiracy nuts called. They want their tactics back.
Maybe the reason why she dismisses the Disney heroines is because most of them don't slavishly adhere to contemporary feminist values. To judge the protagonist of a fictional story according to your own value system is an exercise is close-mindedness. If you judged real people that way, you would be criticized as a racist, sexist, homophobe, anti-immigrant (oops, don't know why that slipped out), so why should someone get a validity pass for saying some fictional character's value system is "wrong" because it's not in line with 21st Century left-wing neo-feminist thought?
But bean-counting for the sake of anecdotal evidence is never healthy, since it often reveals the bean-counter as a hypocrite when the tally doesn't go her way. When I got involved if SF fandom back in the late '70's, there was a small but very noisy entourage of young, female fans who regularly denounced every male SF writer they judged as "sexist", based on his work rather than of any actual knowledge of the man himself. E.E."Doc" Smith was one of their favorite whipping boys based entirely on the premise of his Lensman novels that only males could Lensmen. Now, almost thirty years later, every one of those no-longer young women who is still in fandom worships at the altar of Joss Whedon, creator of Buffy The Vampire Slayer. Do you think any of them has a problem with Whedon's insistence that only women could be Slayers? I wonder what happened to all that fiery egalitarian spirit when the tables got turned.
