Is this sexist to have women only times in swimming pools?

I'm not the sort of person to get offended by ignorant people on the internet, so before I do, I would like to clarify.
Are you saying that because I am a human male, I will stare lecherously at human women, BECAUSE I'M A GUY?
If you are then in my opinion that comment is far more sexist than a leisure centre hosting female only swim classes.

The suicide rate of men is much greater due to reasons of body issues and not feeling attractive to men. Men feel exactly the same but are more ashamed about speaking out for it, I know men who will never take their shirts off in front of women even when I don't worry about what they think. People have to understand you'll get everyone looking at your body regardless what you look like, if anything inappropriate happens just tell the lifeguard to remove that person, don't view one gender as all the same.

I think it's a good idea for religious women have their own session but the idea of women only seems too backward for me. I may have a female friend wanting to join me, say it happens again am I suppose to wait in the changing rooms while she can stay.

I don't think that making concessions to barbaric beliefs is the way to go.

but, to some degree you have to respect what others believe even if you don't agree? I don't know, I hate this whole thing tbh

Would be much better to just have a separate, smaller pool. That way the timings don't affect anyone.

Who will pay the building and maintenance costs?

So if a group of white people said that being in the same space as black people "made them feel uncomfortable", do you think that would be acceptable?

I don't think it's fair,

but you have to understand some women cannot exercise in front of men (for religious reasons) and so many women have been help back by being self conscious; as many studies show women, after school exercise significantly less than men on average, and much of the time this is due to being self conscious. If this helps them, and offers the religiously inclined to exercise freely when they usually can't, it's only an hour or so of the day that men can't go, and if they cannot go at any other time... I mean do you at least see why it's necessary, even though it's unfair?

Who always pays? The consumer.

You're making a really big deal out of this. What does racism have to do with this situation - it shouldn't have been brought up here.

You mean the taxpayer?

What some people don't seem to understand is that if you since the age of 9 been sexualised and have had lewd messages shouted at you in the street, you will find it uncomfortable to by in a swimming pool half naked with men. Because when you get shouted at and have had sexual demands screamed out you but builders or a group of men on the street, when you wear wearing just JEANS and a TURTLENECK, yes you will feel uncomfortable wearing a swimsuit in front of men because you haven't seen it any other way. OF course its not all men but when you have experienced so many incidents of public ridicule then how are you supposed to think otherwise?

How is it different from when some people say that Muslims are all terrorists/rapists/intolerant? - something that people like you are so keen to denounce.

If it is that big of an issue to men then men should demand a male only session rather than say that female only sessions should be removed. If you want to swim with a female friend then she can choose to go to a mixed gender swim session (which most are). All you need to do is check the swim times before you go so you don't go during a female only session. Female sessions are popular and there is a demand for them, why take away something that helps more people get in some extra exercise?
