It's not freedom to choose if you've spent years being raised in a sport culture telling you that women can only be judged accurately if they're nearly naked with heavy makeup, but that men can be judged accurately in baggy shorts/joggers without makeup.
Choices are not made in a vacuum. If you want female gymnasts to genuinely have the freedom to make real choices then the sexism and sexualisation needs to first be removed from the sport. Until that is done, nobody has freedom - neither those wearing sparkles nor those in unitards.
When people point out that women's gymnastics has sexualised dancing and essentially judgements on attractiveness, responding with "that's how it is" or "the men's competition isn't set to music" is not the defense you imagine.
It merely highlights the default sexism and way people have been socialised not to even see how sexist it is.
"It's normal for gymnastics" - yes, we are aware that sexism and sexualisation of female athletes has been normalised in gymnastics, but that doesn't make it acceptable or defensible.
Why do the men not have to dance and wink to show character? Don't just tell me that the men don't perform to music as if that makes it all ok, justify why that is the case for the men but not women.
Don't forget that women were initially excluded from the Olympics, and have only slowly been allowed to compete in restricted categories based on a continuation of that sexism and views of women as inferior athletes who are there for decorative purposes.
"The Olympics have always been sexist" is not a good reason why they should always be sexist.
