The Caucasians way is wrong too and two wrongs don't make a right., but it is easy to point fingers. It is a given that we like to act differently and we're not who we're pretending to be.
No one is wrong, people should have the freedom to decide for themselves.
If enlarging your breasts is ethical, if enlarging your butt is ethical, if enlarging your eyes is ethical, if straightening your nose is ethical, then whats wrong with enlarging your limbs. If its medically safe and possible, then why should the society get to decide for an individual whether its ethical or not?
If a person is insecure about something and has the means, s/he should have the freedom to do something about it.
