I would show my points of the pro-side. First and foremost, even though some people like MJ tries to change the black skin to white skin, it's hard to change from head to feet, the body structure is a thing that a man could never change.
Second, some people look down upon their race, so they would change their appearance at any cost. This would cause a bias of all races. Each race is equal, there's no disadvantage,each of them is unique. If we ban this motion, there'll be fewer racists.
Third, medical procedure may raise the trend of cosmetic surgery. Because people are always wanting to be beautiful. They are not satisfied with their appearance. If there is one example, other people will follow.
