I don't see how appreciating someones beauty even though they've had plastic surgery is shallow? If anything I'd think that disregarding them because they're not naturally pretty would be rather shallow.
Since we are discussing on how it is nice to view pleasant things, we as humans are made to appreciate good looking faces, whether on females or males. It is something that goes on in our brains. Now, if you add in plastic surgery, if said person is in motion, their plastic surgery work is really obvious, and we enter something similar to the uncanny valley in video games.Aesthetics are shallow. They always have been. Appreciating aesthetics does not mean you are disregarding everything else. Also, having shallow admirations that are not at the expense of other things is not inherently bad, and there are many other areas where people receive things in this way and it is not looked down upon, making them hypocrites. I wrote about it on my blog once, so I'll just copypaste that here.
I was speaking about typical happy-mood kpop specifically when I wrote this, so obviously I recognize that not all art is marked by pleasantness, but can have other purposes. Also, in view of my points on natural vs cultivated quality, in non-talent areas like the visual side, plastic surgery is a choice the person makes, to close the gap. To me it is no different than that hypothetical cook with no sense of smell getting a surgery (which doesn't exist) to give him a better sense of smell.
It is a practical thing for a practical purpose that is realistic about the nature and roles of pop arts and human nature that we can't change. If the person who gets plastic surgery has a really solid understanding on these things, like say, the Brown Eyed Girls, I think that is actually pretty cool. If you are deeply bothered by it because it is more permanent than styling your hair or clothes, and that makes it "different" then you need to articulate why that difference is apparently bad to pass judgement on the practice. Your feelings do not determine truth for the universe.
Also, bear in mind that a picture doesn't show a person's heart, it shows their image. If people here like someone for their artistry or character or personality, they aren't going to post a picture of that person to share those things with others. They'll probably link to performances or post a translated interview or variety show, and that does happen pretty often.
Also, the main problem with anyone getting plastic surgery is that it comes back biting them in the ass in the future. Human faces are meant to grow in a specific manner, but places where plastic surgery jobs were done don't really grow properly. So what happens, you see a lot of uneven places in the face, and that in general is really unpleasant.
On top of all this, I see it as shallow because it's as if people are saying "yeah, you did not look good before plastic surgery, but after plastics, you are totally attractive". This gives the impression that normal girls are not attractive by nature.
Since we are on this subject, who are natural in KPop? Only person that I know is natural is Jyuri from KARA.
