I suppose you can provide some articles to show us where they find this so amusing? I haven't read that anywhere except on FR from the evos who occasionally make that statement.
Actually, America rose to prominence in the world of science before the Supreme Court imposed the Lemon Test. The idea that we'll fall behind the Chinese, Indians, etc., because of failure to teach evolution as fact, as opposed to theory, seems rather silly.
The Chinese & Indians may be laughing at our educational system, but it's because our system is obsessed with egalitarianism, political correctness, diversity, and other such nonsense, which is mostly brought to us by the same people (ACLU, People for the American Way) who went to court to get those stickers thrown out.
