By that logic wouldn't your terrible genetic disease be just as much a part appointed by God as you blue eyes? If it is wrong to doctor your appearance then it would be wrong to doctor the disease. 

It seems to me that appealing to randomness to make you not feel bitter about ones parents decisions is a weakish argument. Sorry but I really don't see much to go on here other than 'its not natural'. Your parent already exercise some control as to your physical appearance via the choice of partner. It is the same distinction between naturally selecting crops and genetically engineering them. Maybe you can restate this to clarify it for me?

How does the fact that it dosent matter to the child lead you to 'well the president could make the decision'. Parents (mothers prebirth IMO) are responsible for decisions effecting their child and just because it is unimportant dosen't magically give the president a right to interfere. Pretty sure people would get up in arms if Trump started mandating genital mutilation although it is a little hard to tell with his supporters.
