There are always some aspergery retards that love to shriek "racism", while the rest of us roll their eyes.
For it to be "racist", we would have to be implying that there was some inherent defect in Korean people, and even then, it might not be demonstrably racist.
The Koreans have selected a cockpit culture and business culture that does not work as well with aviation safety as modern Western nations do.
American culture of the 1800s would probably be just as bad, for example.
Point is, the Koreans have adopted an attitude toward aviation that is based on their social culture, which is very ego-oriented and does not allow for admitting mistakes in a goal-oriented path to safety.
Instead, it is paramount that the human ego be protected from embarrassment, with aviation safety taking a subordinate role to the preservation of social status.
Americans and Europeans, while imperfect, are more comfortable (ON AVERAGE, RETARDS) with saying "oops, I screwed that up". This acceptance of human fallibility is CRUCIAL to CRM and having a safe flight environment.
But for those whose emotional hemorrhoids are already itching and burning to scream "racism" at the top of their quavering lungs, relax, lollolzlzl!!
The gun-slinging machismo of the American West would have been just as dangerous, and them was some white guys!
