Okay so meaning of this episode is the Indian Aryans get shutdown by the white aryan moderns.
The white aryan moderns are their own worst enemy. Basically one modern white asshole ruins the city for everyone else. And eventually the hero, rarity, saves the city along with pinkie pie who represents the Rational Man. The episode encourages rational diversity rather than liberal diversity, for instance, Eureka is a show about rational diversity, as there is one cool black man in the show. Liberal diversity is more about flooding in blacks en masse and having them take over cities.
In Eureka and My Little Pony, the black man and black woman live outside of town, and are friendly easy going and cool helpful people.
