What's controversial about quoting Japanese students talking about their own comparison of Japan and America?
If you really want to drop controversy, how can this thread even amke sense? It's about comparing societies asking if one culture promotes "better" people than another - what part of that isn't controversial in and of itself?
Here's an idea: why not focus your comments on your own culture rather than another that you only have very limited first hand experience with? That might work.
