I can see his point actually.
I don't really see the need for a women's hour at a gym. According to the man in question, the gym justified the women's hour in terms of allowing women to avoid harassment. Totally ignores the fact that women can harass other women.
I think it would be much better if gyms had clearly written harassment reporting procedures, so that all the patrons of either gender knew who to talk to if they felt they were being harassed, and knew that their complaint would be taken seriously. I've signed up to a few gyms and can't recall ever being shown one.
I can also understand why some men feel they get a raw deal from feminism, or at least some of the things that famous feminists say. I've see women say some awful things about men that simply wouldn't be tolerated if men said them about women, or women said them about other women. Taking the example from his article, can you imagine the poo storm if Giles Coren had said he'd rather die then have a daughter?
