I hope you are not expecting me to take seriously an objection based on your seeing an announcement of public lectures when you were a Math grad student at Yale! You are talking to someone who has spent most of his adult life on the Arts side of campus, who has sat through hundreds upon hundreds of Arts lectures in dozens of courses, who has listened in his office to complaint after complaint from Christian students who report bad-mouthing of their faith by other professors, who has himself experience anti-Christian edge when being interviewed for undergrad teaching jobs by atheists, Marxists, deconstructionists, etc.
You’re a Math prof, not an Arts prof. You were a Math student, not an Arts student. Your adult life has been spent talking to people from the Science side of campus, not the Arts side. So either you have to remain neutral on this question, or go along with someone who knows the territory well. I know the territory well. And I can tell you that undergrad profs in the Social Sciences and Humanities frequently denigrate Christianity and religion generally, sometimes obliquely, sometimes quite directly. That has been the case for at least 40 years, at most universities on this continent (excepting specifically denominational institutions).
You probably are less likely ever to have seen this, since Math and Science and Engineering, by their very nature, rarely deal with “values” or metaphysical or religious questions, whereas the Arts subjects cannot escape them. The prejudices of the faculty members inevitably come into what they choose to study, what conclusions they come to, what they think should be on the curriculum, who they think should be hired, etc. The personal and professional are nowhere near as easily separated as in your academic area.
The biases are especially strong in religion and philosophy programs, which tend to be taught by secular humanists or ultra-liberal Christians and Jews who are hostile to more traditional or conservative interpretations of their faith. Their students quite often feel that hostility.
Sit in some Women’s Studies lectures sometime, and try to determine whether the average Women’s Studies professor gives a “balanced treatment” of the story of Adam and Eve, i.e., leaves the student with the sense that the traditional Augustinian interpretation of Adam and Eve might well represent the truth about man and woman and therefore should be treated as a serious intellectual position alongside modern feminist positions.
