Should sex-segregated swimming hours be established in public pools?

[RevStPatrick]

17. There's a public swimming pool near my house...

...here in Brooklyn. It's an indoor pool, open year round.
A few years ago I thought about joining, thinking that I might like to swim laps in the morning before work. I went there one morning to check it out and join, but they wouldn't let me in, because it was "Ladies Swim" time. They do that 3 mornings a week.

Those are the hours they close the pool to men, so that the Orthodox Jewish women can swim. There's a large Hasidic community in the neighborhood, and they got this in the pool's schedule.

Should this be OK?
I think it's OK.

I wasn't offended by that. I didn't join the pool, partly because I wouldn't have been able to swim during the hours I wanted to swim. But mostly because just from standing in the lobby for 2 minutes, my eyes burned from all the chlorine. I could only imagine what it would have been like to actually be in the water...
