And I seriously doubt that Concerned Alumni of Princeton "fought integration of women and minorities on campus."
First of all, why the faux shock at the concept? The reason why it took so long for women and minorities to be integrated into many colleges, elite and otherwise, is that lots of people "fought integration of women and minorities."
But, in any case, here's PFAW providing us some information:
# CAP complained about the admission of women to Princeton. T. Harding Jones, Alito’s classmate and CAP’s executive director in 1974 (two years after they graduated) told the New York Times that “Co-education has ruined the mystique and the camaraderies that used to exist. Princeton has now given into the fad of the moment, and I think it’s going to prove to be a very unfortunate thing.”1
# CAP also complained about the admission of minorities to Princeton. An alumnus wrote in 1974 in CAP’s magazine that “We had trusted the admissions office to select young men who could and would become part of the great Princeton tradition. In my day, [Dean of Student Affairs] Andy Brown would have been called to task for his open love affair with minorities.”2
# CAP repeatedly warned that the admission of women and minorities would undermine the university. A 1973 CAP fundraising letter claimed that “a student population of approximately 40 percent women and minorities will largely vitiate the alumni body of the future.”3 And in 1974, T. Harding Jones claimed that “Annual giving has been hurt very substantially by the equal-access vote.”4
# CAP supported a quota system to ensure that the vast majority of students would continue to be men. Asa Bushnell, then chairman of CAP, told the New York Times in 1974 that “Many Princeton graduates are unhappy over the fact that the administration has seen fit to abrogate the virtual guarantee that 800 [out of roughly 1,100] would continue to be the number of males in each freshman class.”5
# CAP opposed affirmative action for women and minorities but supported affirmative action for athletes and the children of alumni.6 For instance, CAP principal John Thatcher argued in 1974 that “Academic weakness below the projected graduating level, or character defect, should be the only grounds for rejecting athletes.”7
