I think when you swap south korea for canada, which is pretty culturally identical to america, you lose all the history of racism against eastern people and countries. So I wouldn't blame them if they did, and I would kind of expect them to actually, and would consider alternate views exceptions or even misguided. Its not necessarilly bad but it looks pretty bad.
It works both ways though - there is plenty racism from many in the east against western people both black and white. As a (very!) white person I've experienced this first hand in several places in Asia.
