I agree with Eliezer, though. I'm a man, and I don't find the lack of fully realized male characters in MLP particularly disturbing (*). I think it would be unreasonable to demand every work of fiction to forgo the use of stock characters. MLP is a show about female ponies and their female pony overlords ("overladies" ?), and that's already about 7 characters right there, so it's reasonable that the rest would end up as stock archetypes. There's only so much attention to go around.

(*) Though I only watched the first season plus the s02 pilot, so I could be missing something.
