I thought lesswrongers were more free of preconceptions than this.

Preconceptions are also known as priors and are necessary. Maybe you want to accuse me of having poorly selected priors, but my priors in this case are not ex nihilo - they come from three decades of familiarity with the product line. The specifics I mentioned - coloring, naming, combing hair - are references to empirical evidence available to me concerning My Little Pony. If you want I can provide links.

Thank you for providing the summary. I notice you were downvoted to -1, not by me. I'll bring you back to 0 by upvoting, in appreciation for the summary. However, the story itself seems to me to be fairly generic among decent didactic children's stories.
