First Response: I don't really know about anywhere else, but here in Indiana, I don't see ponies or Bronies anywhere. I have never, in person, met another Brony, I don't know anyone who has ever mentioned the show let alone watched it here. But that's just from my perspective, it could be different in other places.
Second Response: We a distilled with the the knowledge of right and wrong growing up by observing the world around us even if we are not taught it, so that point is mute, the show doesn't teach these morals, it just re-enforces them, and that is something the world could use now a days... Seriously.
Third Response: The Humor and references of the show are subtle but apparent to those of classic taste. I agree with Incognitokiwoy, the show doesn't need that modern random somewhat obscene humor for a show to be original and great! call me old school but I find the classic cartoon gags they through in the show hilarious just for throwing them in there! I guess you just have to be older to appreciate something like that.
