Simcha613: “(though I assume and hope they have their own poskim making these decisions)”
You’re going too far out on a limb trying to be find a zchus in wrongful activity. If you walked by and saw a group of Jewish teens through the windows of McDonald’s having a jolly time partying eating cheeseburgers and shrimp with cheap goyish wine, you wouldn’t “klerr” that “I assume and hope they have their own poskim making these decisions” allowing them to party in a treif McDonald’s with cheeseburgers, shrimp and wine. Nor should you klerr as such about MO bungalow colonies with mixed swimming, MO shuls with a three foot “mechitza” and a social hall with mixed dancing, MO teens keeping a “half Shabbos” while texting each other, or those eating in non-kosher “vegetarian” restaurants simply by deciding it is okay by simply looking through the list of ingredients. (Only when “away from town”, of course.)
Nor should you make that deduction regarding girls schools that have a mandatory Gemora class (or virtually mandatory, where it is socially unacceptable and embarrassing to opt out and/or they are enrolled by default.)
