回复：I am NOT supportive of dual citizenship.

The Chinese government's policy almost seems to treat citizens who decide to take other nationalities as "betraying" its motherland, and therefore automatically waives their right to be a Chinese citizen.  It's probably carried down from the Mao years, when China did not have many friends in this world and mostly enemies. 

Honestly, I don't know if I will take dual citizenship, even if allowed.  What's the point?  If I love China so much I should just go back and live there and be done with it.  If I prefer US then I will remain here and visit other parts of the world as I choose, including China.
