If our current President is cheering for other than the USA, that is wrong. Look, I don't like the way Ms. Rapoine expressed her opinions as to President Trump, using the F-word, but I understand her opinion as to the general political, sexist and woman abusing opinions and ways of Trump.
While I tend to agree with you, I do see commentators who totally ignore a male athlete who mixes the "F-bomb" into his daily conversation, but take offense when a female athlete does the same. I had the same feeling, then I had to catch myself and ask, "Why?"
It is our upbringing, I am sure - and I am showing my age now. In this era, we are supposed to accept than men and women are equal - and thus we cannot make separate standards for their etiquette and presentation. I am uncomfortable, too, but I accept that.
Win or lose the final, the USA team have already been invited to the US Capital by some of the progressive Democrats like AOC and I have no doubt politicians of both parties will participate in honoring them.
And Trump will be tweeting his indignation for hours!
