This may upset some people here but I think one of the reasons that Eileen Gu triggers so many people is that her personality shares similarities to that of Donald Trump. Let's not kid ourselves here. When confronted with aggressive and unfriendly questions or abusive reporting she fights back in very trollish manners. "Uneducated people who won't win any Olympic medals", if you really think about it, is just a nicer, more eloquent way of calling her critics "losers".
Trump supporters don't like to be on the receiving end of this sort of abuse.
