^...what on Earth are you talking about? Throwing words like "sexist" and "racist" like that...
You're comparing Japan to S.Korea to "the West" in such a weird way.
Did you know that regardless of their origins,people have the right to dislike (over use of) plastic surgery .-. ? Let's say I love Beyoncé, Katy Perry, Nicki Minaj, Rihanna and whoever you want. Does it mean that I want my idols looking like them? Does it mean that I want Fuku-chan with NickiMinaj's body?... hell no. Your last point makes no sense. The reasons we love International stars are not the same reasons we love idols/H!P girls. Also, don't say "every single Western country entertainment relies on looks and PS". Looks ? Sure. PS? No. That's just wrong.
As far as I'm concerned, I like my idols rough and ready. Eyelids tape, make-up, braces and different hairstyles should be enough tbh.
Btw, Wotas tend to prefer the "pure, Japanese" look (*coughs* Riho*coughs* Sayumi*coughs*). This and chara are more than enough to be popular.
Finally, what's the point of using a picture of Gomaki? That was like ERAS ago...
I may have used racist the wrong way but it very much is sexist.
I'm comparing Japan and S Korea cause its very much talked about on Asian pop forums in general. I mean look at english youtube comments on jpop videos and you will see that jpop fans going for kpop idols looks while kpop fans go after "crappy music".
You can dislike plastic surgery of course FOR YOURSELF, imo you shouldn't judge it on other people due to the fact that its their bodies.
2/4 people you've named has had surgery, only one has a super obvious one. And Beyonce and Rihanna are considered one of the most beautiful women in the world so idk where you're going with this "you don't want your idols looking like them" but I'm not gonna go any deeper with that.
Anyways:
Fuku-chan doesn't care what you want. If she wants to have surgery, I'd be surprised but thats her thing, not yours. Would you get mad if she dyed her hair blonde too? Would you get mad if H!P put non East Asian foreigners in Morning Musume and they're not as "pure" as you want them? You seen to have an intense description on how you want your idols to be.
I used Gocchin because even though its years ago, jpop fans still dont believe that idols alter their face or do non idol-like things ever (smoking, curse, hook up). Theres a lot to criticize kpop about, what their female idols did to their faces isn't one of them.
