One thing I found pretty funny is the way that the hottie female host Isobel Yeung, got all "wet" when the doc she interviewed confirmed that "height" was going to be a trait that will be preselected by future parents. I guess she said fck it to being politically correct about genetic engineering if it meant eliminating short people from the human race.
I really hope this statement of yours isn't going into the direction of the theory "women are hard-wired to be extremely attracted to tall men because they inherently seek the highest-quality genetic material for their offspring, all women, whether they will tell you or not, actually want a really tall partner." Because I think that's bull . Now I don't know the reaction of the lady you were talking about, but shallow people simply exist, they are a real thing, but they don't represent all men or women. And you shouldn't really hate people for having preferences - I know this feeling of course - I have often felt disgust towards a woman who shows she reallly likes tall dudes, but in my logical opinion, she should be allowed to have preferences, because I have them too. What I would find bad is when this "must be tall" preference would be extremely vital to her, and not just one thing out of several that she likes. But again, I don't believe this represents the majority of women.
I welcome this advancement too, it's good for the greater good of humanity. Unfortunately there are going to be abuses of this.
I'm no expert on the subject, but I'm critical of these trends. When it helps to eliminate serious issues such as medical conditions, or diseases, these genetic advancements could be beneficial, but I think that genetic variety is a good thing. It can help to shield humanity as a whole from genetic disorders, diseases and other disadvantages. The whole thing about selecting which trait is better and which deserves to die out is highly serious and questionable, and history has shown us it can also be dangerous. It's the dystopian fantasy from "Brave New World". From a personal standpoint, I love diversity and I'm thankful for all men and women who are my height or shorter.
