Are you for or against 'Designer Babies'?

Scientist say it is time for a serious debate on this matter as technology breakthroughs make designing our babies possible. Babies genetically modified for beauty, intelligence or to be free of disease.

An ethical society may argue against ever do such a thing where another society/country may use it to build a super race of athletes and soldiers.

Just because we have the technology to do something, should we? What are some possible unintended consequences of playing God here?
