Americans are mentally weak
Ignoring the fact that the U.S. Women's Gymnastics Team saw their best gymnast -- the consensus best gymnast in the world and the best to ever do it -- drop out of competition one event into the Olympics yet still had the mental resolve to pull together and nearly win the gold medal ... it's quite possible that people in general are mentally weak.
The difference is that it's socially acceptable to show that weakness nowadays. Well, unless you're black or brown.
Look at Sha'Carri Richardson. Girl said she smoked weed to mentally cope with the death of a family member.
Now, taking that statement at face value -- personally, I think she smokes recreationally or whatever but that's not why we're here -- and knowing the side effects of marijuana, that's a move she made to take care of her mental health. Just so happens that move is clearly a "don't do that" in the rules of her sport, thus in my view she deserved what she got. She got killed on social and all that.
People in here are talking about how Serena would get crushed in the media if she did what Osaka is doing. Likely. I think the reason for that is based in image.
Sha'Carri and Serena are portrayed as flamboyant, loud, emotional, passionate, ferocious, arrogant individuals. Osaka/Simone, to the best of my knowledge, have this "polite sweetheart" deal going for them, though the argument exists that Biles is leaning into the arrogance thing after rightly acknowledging her undisputed status as GOAT.
It's unfortunate that her mental issues got the best of her when they did, but when it comes to shyt like that, you have to look out for yourself because nobody else is required to once you're an adult.
