So, you are saying that compersion -- feeling happy and joyful when your partner finds happiness and satisfaction with their other partner(s) -- is "strong" in the cultures you mentioned? That would mean they have a polyamorous history, then. I assume you are saying it is part of the heritage and history. Or are you saying it is strong in contemporary culture? Can you explain this and cite examples?
