I was watching pro golf coverage on the news and it seems so odd that men and women compete separately - same goes with pro bowling. Just seems weird to me that a game of skill is gendered when you can’t even raise an argument that someone might have an advantage because of what’s between their legs.
#2 May be explained by mens’ sports being given more support wrt to training/coaches/funding/etc. Here is an interesting article about it: https://www.theatlantic.com/culture/archive/2022/09/sports-gender-sex-segregation-coed/671460/
