Goodness - next time you're at Disney, take a real close look around.
Pirates of the Caribbean? NOT a nice buncha fellows (and don't forget about Anne Bonny). Murderers, theives, the whole nine yards.
Cinderella? In the original Grimms Brothers story, the evil stepsisters were forced to wear iron shoes heated red hot ..... and dance in them until they died.
Snow White? As I recall, her stepmother paid someone to tear her living heart out...... and Snow ended up living with a buncha bachelors in a hideway in the woods, under somewhat dubious circumstances.
"Why on earth would these characters be considered to be suitable in a theme park frequented mainly by children?"
