Is the women's area alone in the gym a little sexist?

Yes, I think it is.
I'm a woman. I go to a gym with an area just for women and with a mixed area.
Under no circumstances have I seen men being disrespectful or inconsiderate to a woman. Yes, if you are handsome, you can take a look, as we do with men!
At the same time, I've noticed that when you go to the section for women only, the area is often used by self-managed brats, who are much worse at judging or just average.
I think it's a waste of space and resources.
We need to understand that men are also part of our society. How are we going to convert the country? Saudi Arabia?
