It's not about hating Korean people. Most of us have had a mostly good experience with Korean people being friendly, but there are certain aspects that, when you are raised in America, Canada, the UK or other English speaking countries, it allows you a perspective that Korea is not just insular but it clings to being insular at all costs. Mainly, to avoid its citizens from even admitting that other cultures could be on to something when it comes to being progressive on the subjects we are discussing. It's a dazzling amount of self promotion to avoid the darker truths that permeate this society. America, on the flip side, has social problems of its own but we discuss them publicly. We brainstorm on how to reduce them. We strive to make them visible. Typical Korean thought is to ignore whatever you don't want to look at or confront.
