This is piss poor for the US, but not at all surprising. Why is it not accepted? Because it's not stressed enough in school. People are not forced to think its implications through. In short, people don't understand evolution. It's not particularly surprising that they're not sure what to think about it when they don't Know anything about it to begin with. The solution is education. Perhaps people like Dawkins could try to get more specials on channels like National Geographic, where evolution is explicitly addressed in length. Also, whoever writes science textbooks, should relate everything in biology to it over and over and over again throughout the book (and not just biology, but all topics). After all, evolution is related to or easily related to any topic relevant to life, so it could readily be incorporated in an effective fashion.
