America, historically, has been defined by a Protestant culture which places a lot of religious and moral significance on conceiving human life, and on God's role in creation. Chinese culture does not, as far as I know, have the same stigma against genetic engineering (I admit that while I have traveled for some time in China, I am relatively unfamiliar with any moral, religious, or cultural issues they may have on this topic).

It's natural for the GP to assume that his or her morals are the most correct. How could they behave be otherwise? If they believed that Chinese morals were a higher standard, they would adopt them. Everyone reads the article from their own perspective.
