Says one paper:
There is increasing acceptance of family balancing as a reason for sex selection, but some people remain opposed to broadening the indications for sex selection of offspring beyond family balancing. Nevertheless, parents may have good reasons other than family balancing for choosing the sex of a future child. Such reasons may be justified by the principle of reproductive liberty.
The impression that I get is because sex selection abortion won't lead to widespread gender imbalances, it's okay.
Interesting idea.
