AREN'T THEY SMARTER THAN WHITES, LOL? (btw, I'm white). Anyway, the last thing I thought of when I read the OP's first post was a racist comment. BTW, I noticed people from Scandinavian countries tend to have light hair and blue eyes...is this true, lol? As the OP stated "I am wondering if I'm imagining this."
I think an observation on personal experience and asking if others have encounter it is a legitimate question. If anything, I thought it was a compliment to Korean women, lol. I didn't take anything derogatory from the comment nor do I think that the OP meant to imply Korean women are superior to all other races. It was just a simple observation based on experience.
OP, feel free to clarify. Maybe you did mean Korean women are superior to all other women. In than case, you are a racist, lol!! (only kidding with you).
