Your statement that "it's only legal and socially acceptable in one direction" is factually incorrect. There are hundreds of examples of male-only clubs in the US. Every Free Mason lodge, all Catholic seminaries, golf clubs, the list goes on. For example,just a few weeks ago Pine Valley (the number one golf course in the US) just voted to allow female members for the first time in its 108 year history. They aren't legally obligated to allow female members, as a group they just finally decided to open the club to women. It took them 108 years. If that's allowed, I don't see why this women-only group shouldn't exist. Maybe in 108 years they'll decide to allow men. https://www.golfdigest.com/story/pine-valley-women-members https://www.golfdigest.com/story/pine-valley-women-members
