My point is that preferences are malleable and there is no objective reality or grounding in modern society for short stature being an undesirable trait (at least going forward). My hypothesis is that short stature historically has been attributed to malnutrition, and therefore destitution as well, which has shaped modern day preferences, but perception lags reality.
EDIT: Also I should add that people are reading my comments automatically into the context of sexual preference, but I was talking more specifically about the general attitude that it's ok to deride people based on their genetic shortness. That being said, even if OK Cupid (Which is just a proxy for dating preference due to the specific nature of how it operates) showed that black woman were the least likely to get matched on OK Cupid doesn't mean it's ok to now make fun of them based on their skin color / cultural / racial background. Our perceptions about short people, black women, etc, are the results of social conditioning. Conditioned behavior will always lag the current reality. It is my belief that short stature does not hold the negative associations it once had, just as whatever was the reason for our preferences against black woman probably do not hold anymore.
We don't go around forcing people to start liking short people or black woman if they have not conditioned themselves to do so yet, but we also shouldn't be accepting adding fuel to the prejudicial fire.
