There's a lot of context lost in the research, some of which was even mentioned in the comments. Why would women in medieval or 1800s Europe hold the balace of power? Isn't the point of Belle being "odd" is that she's different from the other women in town? If Mulan joins an all-male army, shouldn't there be more men with speaking roles in the movie? If a story is called "Snow White and the Seven Dwarfs", don't we know what we're getting into? If the name of the movie is "Aladdin', I'm going to expect the story to be about him.
The research also fails to discuss the merchandise line, which is the more widely viewed version of these stories, as these movies only come out once every 7 years. Or other versions of these tales, or what other things a child is exposed to in their upringing beyond a dozen animated features (not all of which a child will see).
