“how many very very high up private goyish schools have separate classes? a lot, exactly because of this”
As I pointed out, the number of all male secular colleges in America is now down to three.
My grandfather z’l was very opposed to coeducation. He was an English teacher and real traditionalist in education. But now colleges and universities are run too much like businesses. You have to give the customer what they want. And that means lots of As and lots of “social life” possibilities. I can’t follow the opinion that coeducation is asur because Rav Soloveitchik was my rav’s rav (and I teach in one the graduate/professional divisions of YU, all of which are required to be co-ed), but it is a shame that there are now so few single gender options for those who want them.
