Personally I find it depressing how many people do know of such abuse and think it's good, okay or at least never take any action against it.
Also, sure, we never know what people are like behind closed doors... but I think even if we do know them personally... do we really see them for who they are?
(Overall, another case that shows that figure skating in general has a problem. These cases are not isolated. The hierarchies, the power of coaches and feds, the very young age of the athletes and the whole culture of figure skating which glorifies training and competing with serious pain, starving yourself, accepting whatever is thrown at you, "respect" for coaches no matter what... all these things are a problem. Looking after yourself, listening to your body, trusting your gut feeling are not aspects that the sport overall values.)
