Beacuse the points you are making are lame and unconvincing. How does it matter for a Chinese or a Japanese living in his own country what's the average height of a far way land that's 1000s of Kms away. He's not gonna date caucasians nor work in a caucasian environment and everything in his country is catered for the average height in his county. The situation you are saying where he emigrates to caucasian country and meets a racist caucasian "sometimes" is far fetched and irrelevant. You think a white guy will be treated well in China beacuse hes taller? Anyone who's minority in a country will be going to be discriminated for a dozen other reasons other than height. "Any" height discrimination is a pathetic criteria for deciding who's short. 5'10/5'11 average Americans are rejected by women all the time because most women wan tall guys who are atleast 6 feet. We gonna call 5'10 americans short now?
