The problem is that the value of diversity, as our thought experiments showed, can conflict with the value of individual choice. As a society, we may feel that it is profoundly beneficial to the community to have people who are short and tall, gay and straight, placid and tormented, blind and sighted. But what moral right do we have to require another family to forgo a desired genetic intervention simply for the sake of adding to the diversity of society? Would we want the state to require that of us?
