What exactly is "cultural purity?" I think I understand the concept, but I'm having a hard time putting it into words.

Answer 1

I have nooooooooooooooooooo idea

Answer 2

Cultural purity would indicate the strict maintenance of the customs and ethics of a particular society. Example, in America it would be extremely difficult to maintain any sort of cultural purity since the "melting pot" ideal is the basis of this society. In any nation that is open to immigration for other countries, cultural purity would be difficult to maintain. Very small enclosed communities can "enforce" cultural purity, an example would be certain religious communities.
The best example of cultural purity I could find on the web would be some of the Hindi communities in the Far East.
