And it never ceases to amaze me that those who value education over ignorance would be labeled as "arrogant". Again, I think it reflects a well-known anti-intellectualism in American culture, which tends to value good old-fashioned common sense over education and sophistication. This is why we're rapidly being eclipsed by other cultures who understand that education is the route to power in the real world. The shame is that many of them come to the United States to take advantage of our wonderful-but-declining university system, while American students regard college as 4 years of summer camp. It will be our undoing unless some Sputnik-like humiliation occurs very soon.
Reminds me a bit of how my mother often refers to physicians as being "arrogant", but I think she uses that label for anyone that is demonstrably better educated than she is. Rather than rising to the challenge to educate herself, as some people do, she assigns the flaw to the other person, instead of accepting it herself. In this way, her status quo becomes "normal" and the physician is the one with the character defect. No virtue is so great that it can't be interpreted as a vice when sufficient motivation exists.
