It is sad to see people who believe in such things as ponies being by nature morally superior to, well, humans. That's racism. And even worse (or better, for the show), these assumptions have no canonical base. If ponies cannot do harm to others, then what are they doing thoroght the series? Why does Twilight brainwash random ponies, why CMC brainwash Big Mac and Cheerilee? Why Flim and Flam want to rob the Aplle family of their home? If Equestria is already an utopia, why friendship needs to be spread and taught like an entire science by Twlight during the show? Why there are friendship lessons and friendship missions? Big cities like Manehattan and Canterlot are no friendlier than any human one, and even in Ponyville Flutterhy got horribly mistreated for no reason and CMC are bullied.
