“All of the principals apologize and said that sociologically, this couldn’t work”
I know one seminary head who opposed it for a different reason. What should the girls be doing until they were 20+ or older before they started dating? Many would be in college or working (and there are only so many teachers assistants, office girl jobs available in the community) and they would then be not desirable to yeshiva bachurim because of the secular influences of college or the secular work place. Damned if you do, damned if you dont.
