Regarding golf, the PGA is not a gendered league. Women and non-binary individuals are allowed to play in top level events and several women have done so.

I'm sure to some degree gender impacts opportunity to play golf, but women and girls from families with means do enjoy accessible training and competition these days. Among top non-male players, biology is the greatest limiting factor.

I hesitate to attack women's leagues like the LPGA or WTA. They comes with problems, but also let us watch many of the best athletes in the world compete in their sports. That the world's best female golfers cannot drive as far as male golfers does not diminish their ability to play the game. A good male collegiate golfer can beat an LPGA pro on a typical PGA course setup, the course length of which plays to the college player's strengths, but only through brute force. Women's leagues provide an opportunity for skilled individuals to show their skills.

Those leagues are also important for representation and promoting the game for everyone. If leagues like the LPGA didn't exist, I do not think golf would be as acceptable for women and do not think girls and women would enjoy the access to training, equipment, and competitions they now have. As a result fewer women would reach the heights they do, up to and including playing PGA events.

It's true that in sport gender is often used as a cudgel. However, after getting past blatant sexism, gender in sport is a very complex issue. Separation based on gender comes with some good that should not be dismissed out of hand. It's not on par with something like, "Wet wipes should not be gendered," which is not complex at all.
