I'm just going to try to sum up.
The opponents of cosmetic surgery:
a) claim that people who want cosmetic surgery have some psychological problem like insecurity, low self esteem, buckle to peer pressure, etc.
- This is probably true for a minority. For the majority, it is not. Under all circumstances this would be an argument against specific patients receiving treatment, and not against cosmetic surgery in general. And even then, psych evaluations of breast implantees in general show significant improval in self esteem and such, so since the surgery is effective and actually removes their psychological problem, I don't see why it isn't simply seen as an effective treatment. Are people not allowed to treat low self esteem?
b) feel that people improving their looks somehow diminishes those who don't do it.
- This is a very weak argument. It's like being opposed to thin people because you're of average weight yourself - that's not that uncommon an attitude, but it is also wrong. Imagine if people actually accepted this idea, the consequence would be no one doing anything for their looks.
c) are principally opposed to the idea because of religous or idealistic conviction, like what God intends or what is natural.
- Here I think most will agree that convictions should only dictate what you yourself do. Otherwise you have to deal with the problems of who gets to decide what is right and wrong, as many have opposing convictions. Of course you could have the conviction that you're right and should dictate how everyone should live, but then you're throwing almost all basic ideas of personal freedom out the window.
