The point I am trying to make does not really concern the South. Notre Dame is in Indiana which was the stronghold of the Klan:

I might be guilty of some hyperbole in the characterization of Catholics being MORE reviled than blacks.
This does not change the basic point that the history of Notre Dame is attended by overcoming prejudice and hatred which is the real core of its mythology. In the beginning it is the story of the underdog overcoming large odds. Rudy's story is also cast along those lines even though we might not like the real Rudy. In the beginning most the the football powerhouses of the day, Michigan, Chicago, Nebraska and Northwestern would not even consider playing Notre Dame of the Rockne era for no other reason that it was a Catholic school. Finally, Rockne got a game with Army, travelled to West Point and won! Then the powers of the day started looking like they were ducking ND. In addition, Sperber's book outlines how the school tried to get money from the Rockefeller Foundation. Traditionally such a source would not give money to a Catholic school because it would use the money to teach Catholic theology. ND promised to not use the money in that fashion and became, I believe, the first Catholic university to get money from the Rockefeller. And it helped bring ND into the mainstream of American academia where it resides today. When the president when I attended, Father Ted Hesburgh, came to ND he basically fired Frank Lahey and announced the school was going to excel in academics and not be a football factory.
