Sorry, I’ve come to the edge of my knowledge/understanding, but I wanted to still respond.

Unfortunately, this type of culture isn’t far from my own. In fact, I heard one of the teachers at 세종 say that she (a) studied Yugoslavian languages and (b) came here because we’re Catholic, and she is as well. Anyway, online sources are only better in the sense that they seem to steer clear of those kinds of topics.
