> Kids until they are 18 can be dual citizen of China and American, they just have to decide at 18 which one to renounce

True! But kids under 18 aren't voters not supposed to be a part of the political process, so any opinions they may have is moot.

> Also, attractive female snow boarders are also allowed dual citizenship but those are exceptions.

Yep! Plenty of exceptions all around if you are important enough or related to someone important enough.
