just to say, not all the men are like this though!!!! but i was just considering about those who are? also its not just men who judge but women too, and a lot of the time it is actually just from within the women themselves like you said.
with the stricter men its just an awkwardness thing - like even myself i would moderate myself infront of a more religious brother, compared to if i go to playgroup and some dads are there, there are a couple i do talk to but would be embarrased or shy infront of the religious ones cos u know that they dont wna talk either and its just a bit awkward.
I come across men who would say all this is inappropriate but they probably would not go up to random women and confront them about it though - but some of them do think it and would say it to women in their own family
actually about the inappropriateness etc, i suppose having women only for these reasons reinforces people's thinking that having mixed ones is not appropriate so then if it leads to people saying "there is womens only one, so why do you need to take your children to mixed soft play - haraaaaaam!!!" etc then this is a bad thing for us because instead of this thing offering just an extra alternative to women to feel comfy, then maybe it would go further and then create a restriction but i think most families would be more moderate than that, and just use it as a comfy meeting place for women and kids without taking it further like that?
just to say though i hope i havent given impression people only cover for the sake of what the men think, because vast vast majority of women are doing it for their own choice, because they want to do it for the sake of God. we do believe its told in quran to cover modestly, its not like we just have to do it or men will judge us - so i dont want to give that impression, it may have come across a bit wrong how i said that.
