Dicho, this is probably the kind of guy who would (privately of course) call a brilliant Chinese surgeon who speaks six languages, a "slope-headed gook."
He is so blinded by his own predjudices that he cannot see the record of history. It is not an uncommon fault, ethnocentrism, and it has been around for as long as man has.
There is less excuse for it in this day of mass communicaition and the rapid and cheap disemination of information than there was in 19th Century England where it was an article of faith among a certain class of "gentlemen" that "the Wogs start at Calais."
