Umm... I hope you don't mean talent-wise, because talent-wise she is still far and above most current generation idols. As far as music selection goes, I think her length of time in the industry and age are big factors in that (after performing for so many years, maybe she wanted to mellow out, or experiment, or whatever), so her selection would totally be different if she debuted today. Also, if she debuted today as her current age, then of course that would affect her, because younger artists are generally more favored/popular (not being ageist). But I think if she debuted today as the same age current idols, I think she would be just as successful, because of her talent. 

So... that said, I think BoA was just being modest here and just trying to compliment her younger colleagues. 

What did Sulli's posts have anything to do with you or her haters being so awful and rude to her? 

You want to place the blame solely on Sulli for her suicide, yet you don't want to take responsibility for your hate speech. Doesn't compute. 

The Grammys are held in America - the producers don't go to other countries touting themselves as "international awards". Also, winners at the Grammys are ACTUAL international artists. You can say SOME Korean artists are Asian stars right now, but five years ago, back when MAMA was held in Hong Kong? A bit of a stretch.
