Those who are living an animal don't understand the meaning for fidelity.That is why she is it is overrated.If you are in relationship then this very important.These are part of human value.The a person doesn't posses this qualities then how we can call him a human?
The fidelity she is talking about is western style free market one, which is diametrically opposite to realistic fidelity being practiced since time immemorial by different communities of religion, geography, time, age, etc. Even the tribes which live in total isolation do practice fidelity such as forest people of Andaman Nicobar islands, South American forest people, Indian jungle tribes etc. Fidelity is natural. But temptations are always there. To control the temptation is real civilisation and humanity.
