I agree for deadly genetic disorders, but we can't be sure if a harmful mutation will be important in the future. For example sickle-cell disease make people immune to malaria.
What if in the future a pandemic rises, and we have "edited away" the only mutation that would give immunity?
I think because in Italy the different models are called "man bicycle" and "woman bycicle" ("bici da uomo" and "bici da donna", respectively). How are they called in English?
