I dont know why you think this does yuna look better. She is accusing a few skaters, she is not saying names, so anyone could be included. It doesnt matter if she is speaking about japaneses or not. She is not talking just about feel uncomfortable, she could to feel unconfortable because she had cold, she was sick but not, she was uncomfortable because some skater was in her way, why the need of mentionating if she has not prove that it was on purpose. Even if this was not an accident of the other skater, I doubt that Is the first time that happens. I can imagine what you would be saying if Adelina would be saying something like that.
I didn't say Yuna looks better by that comment. Rubirosa seemed to think that Yuna had kept picking on the Japanese skaters(especially Mao for being her rival) on purpose so I was explaining that she didn't. Anyway, I can see your point too. But she didn't say that some skaters were crossing on her way, she said that she felt pressured(?I can't really explain this word in English sorry), and this interview was really short with Yuna's answer just in the video(I couldn't find what the question was, probably not included), so it was a bit hard to catch 100% what she was saying. Yuna have said that there is uncomfortable atmosphere before the competition usually, so she could have meant that getting bit worse than before. If I have one complaint, it's the Yuna's management company, they just let the problem grow without explaining her words clearly, and quickly.
So, anyway, I've never seen her saying disrespectful things directly or blaminng a particular country or a skater, and this incident IMO, grew big with 'yeah someone said'-all the accurate facts they had were her three sentences. The thing I wrote between () wasn't in the video as well, just picked out from her management company's explanation. So judging whether she had unclassy manner or not based on that isn't really appropriate I think.
