These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Little Red Riding Hood
Everyone Is Jesus in Purgatory: There are lots of possible underlying meanings to the story, mostly to do with growing up and/or sex. The color of the girl's hood is usually given some significance — even though subsequent collection of French folk tales found that it was a detail that Perrault added; the folk tales do not specify the color of the hood. A more likely symbol occurs in the regional variants that have her choose between a Path of Pins and a Path of Needles - girls learning to be young women were said to be "gathering pins," while needles had a definite sexual meaning (prostitutes would even indicate their profession by wearing needles in their sleeves).
Fantastic Aesop: Don't talk to rapists or your grandmother will get eaten. Or something like that.
Freud Was Right: A common interpretation of the tale is as an Aesop about a young girl's burgeoning sexuality, with the wolf standing in as a sexually aggressive man. The red hood is often interpreted as representing menstruation, carnality, virginity, or sin in general.
Nightmare Fuel: Perrault kills off Grandma, then has Little Red tricked into becoming a cannibal, and then she too meets a gruesome end in the wolf's jaws. Sleep tight kids.
