Sofia, in my personal opinion there is an element of systemic racism in the notoriously corrupt structure of the competitive FS world. The largest and most powerful skating federations--the U.S., Russia, and Canada--have so much influence that they are often able to swing judging decisions in their own favor. You sometimes hear bitter comments about the "passport privilege" enjoyed by skaters from those countries, who are likely to be awarded "candies" in scoring and have their mistakes overlooked, at the expense of skaters from less powerful federations.
This could be seen as nationalism rather than racism, but I think it is no coincidence that the big guys are all majority-white countries. Of course, not all the skaters from those countries are white themselves, but IMO they are likely to be treated as honorarily white because of "passport privilege." So I think that our favorite has indeed experienced discrimination (as has Yuna Kim) for being Asian-Asian rather than, say, Asian-American; but it's subtle and hard to pinpoint.
Just my opinion; you may disagree.
