I'm horrified by the prospect of someone or something eliminating maladaptive differences between humans.
Also, your post misuses the word "adaptive". If you tried to design a human male who was evolutionarily adapted to the modern environment, you wouldn't end up with a less aggressive male.
You wouldn't want to pass "maladaptive differences" to your children, if it was a possibility, would you?
Would you like to get rid of them themselves?
That's the intended meaning, I think. Although, once the technical possibility is there, one cannot exclude the probability that some states take firmer control over the genetic code of their citizen than other.
Upon reading Eliezer's possible gender dystopias ([catgirls](http://lesswrong.com/lw/xt/interpersonal_entanglement/), and [verthandi](http://lesswrong.com/lw/xu/failed_utopia_42/) and the other LW comments and posts on the subject of future gender relations, I came to a rather different conclusion than the ones I've seen espoused here. After searching around the internet a bit, I discovered that my ideas tend to fall under the general category of "postgenderism", and I am wondering what my fellow LessWrongians think of it.
This can generally be broken down to the following claims:
EDIT- Due to some really insightful comments;
I replaced men being prone to aggression as a negative, with men being prone to suicide.
I made the verbiage a little more explicit that no one would be *forced* to change, but would seek out the changes that transhumanism would have available.
