I think the solution is simple, if it your shul that this tool place, then you should speak with the Rav ans ask point blank why this is allowed to happen. Then get together with others in your shul to help enforce policy. (Most will have a board and this is a good place to start) There are probably many others who feel the same way. However keep your comments constructive and think of how to make your issue one that people will want to take to heart.
If that doesn’t work, then it’s time to look for a shul that does represent your value system.
Note….I’m wondering why so many are worried about the sake of Klal Yisroel. Between the 3 places where I Daven, (My shul at home at home, my parents and in-laws) there has never been a problem. Nost of the shul’s in my area have strict guidlines where most people are happy to follow. (One of which is a more modern shul with no machitzah by the kiddush and for the most part husbands stick with wives and men on one side and women on the other) Maybe it’s time to look at the good in Klal Yisroel and stop putting a blanket on all Yiddishkeit.
