Designer babies is the start. Like I already believe if you're "selecting" something like your baby's gender, you're fuckin Hitler. But then, my roommate was all, "Well what if you could remove the trait for Huntington's that runs in the family?"

The most interesting case to me is of He Jianku, who reportedly began studying and modifying human embryos. CIA fear disinfo, or Chinese scientists just marching ahead and setting the new standards of the 21st century?
I consider if I had certain conditions, and found out later my parents had the option but chose otherwise... I'd make peace with it, but part of me would be angry.
