“Harav HaGoan”– Rabbi Dr. Revel had been the persident of YU since 1915 or so. Note the “Dr.” Now does that sound MO or Hareidi to you?
By the 1940s, (the period that we are discussing, YU’s direction was already clear. Rabbi Dr. Belkin took over in 1943. Again, note the “Dr.” Both men established extensive secular studies in YU. Now, does that fit more into MO or Hareidi philosophy?
Nevertheless, YU faculty, staff, and students–and their congregations, did a great deal to help establish the institutions such as BMG.
I understand that the MO world will not get any appreciation form such as you until you cross that big river. You know, denial.
