@Sister Bear; Very well said.
I happen to believe that schools arent really out to teach kids but rather mold them into their own version of jews and just try to build a massive army of kids and families that think exactly like they do.
I think if a Yeshiva or Girls School took the road less traveled and went with a curriculam and hashkafa that only the halacha mattered, you could solve the OTD problem on some level. Because the kids would find whatever hashkafa they were comftorable with on their own rather then be pushed into it and taught that their hashkafa is the only acceptable one and everyone else is a “goy”
Basically, turn the schools into actual schools rather than programming centers.
