It is a mixed sex group, then David, not a female only group. Unless words no longer have any meaning.
I sometimes wonder. If men can go to a 'ladies' group', and sometimes outnumber the women so that there is only one lone female, then how is it a 'ladies' group'?
A knitting group where people go to learn to knit, or be taught new techniques may well be attended by men. I follow a couple of male knitters on FB, but they do tend to be 'larger than life' characters who would dominate any group, regardless of sex balance, and I'm not sure how that would work in a more typical knit and natter, made up of retired women who go as much for the natter as the knitting.
Also, some (not all, before knees start jerking
) women routinely defer to men, and are reluctant to talk about some topics in front of them. Men can shift the dynamic, and not all groups would benefit from that. That is why the reading group I'm in decided not to allow men to join. We felt that there would be more risk of being shouted down, or having the ideas we'd expressed being rehashed and presented as coming from a man. Our group can get heated, but it is generally supportive.
They (mostly the husbands of female members) set up their own. They often read different books from us, and from what I'm told the meetings sound far more 'competitive' than ours. Better for all concerned that we meet separately, I think.
A lot of the time, it seems as though men don't want to set up things for themselves. They are happy to go to women's things, or use our facilities, but not to do what women have done for decades, and do it themselves. Maybe they haven't needed to, historically. Pubs, clubs, offices etc were male dominated for a long time, so there was no need for men to set up places to be amongst other men. When women were in the home all day they were more isolated, and going to licensed premises wasn't always an option, so meetings in church halls or community centres meant they could do things for themselves. Also, some religions don't allow mixed-sex meetings, so if men can turn up women can't go.
