>not understanding that fairy-type is based on mythological fey, not modern pixies
Fairies are pranksters, creatures of playful cruelty, thieves, deceivers, kidnappers, nature spirits, shapeshifters, and some of them are even undead. Fairies are not pixie dust and love, with that in mind, most Fairy-types are more spot on than some other typings, like Golduck's strange lack of a Psychic-typing, or how most birds are Normal/Flying instead of just Flying.
