I don’t have a problem with women’s only areas in a gym as the occasional man is a creeper.
But I note they don’t have men only areas. Fair is fair.
FWiW, I’m a member of a gym that requires a combined lift goal of 1000lbs (bench, deadlift, squat) or 20 clean military full pull-ups (no partials). I think it has one woman member and she’s a professional mountain climber.
Men are second class citizens in modern society. Women have all rights, men get nothing. Soon, boys in high school will be punished when schools ban boys’ sport to meet social justice warriors.
"Women Only" gyms fail spectacularly due to low enrollment.
They can pull this stunt at a college because taxpayers and other students are paying the bills.
The men need to demand equal facilities. Watch the fireworks.
So... the behavior of an occasional individual is acceptable grounds for discriminating against everyone else who looks like him, instead of throwing the "creeper" out.

Would you give me the name of this gym? I’d like to check it out. In my 30 some odd years of lifting I’ve never seen a gym that could survive with those rules. EVERY gym I’ve ever worked out in (and there have lots) were always about the membership numbers.
