So far, in my academic career I have not come across this.
Not yet at least.
Interestingly, the survey was done by the

Institute for Jewish and Community Research, [which confirmed…] what the institute’s director and chief pollster, Gary A. Tobin, called an “explosive” statistic: 53 percent of its sample of 1,200 college and university faculty members said they have “unfavorable” feelings toward evangelical Christians.
Tobin asked professors at all kinds of colleges — public and private, secular and religious, two-year and four-year — to rate their feelings toward various religious groups, from very warm or favorable to very cool or unfavorable. He said he designed the question primarily to gauge anti-Semitism but found that professors expressed positive feelings toward Jews, Buddhists, Roman Catholics and most other religious groups.
The only groups that elicited highly negative responses were evangelical Christians and Mormons.

Our colleges and universities are filled with faculty departments that cry “tolerance! tolerance!” for everyone. Everyone BUT the evangelical.
The survey asked how they “feel” about an entire group of people, not exactly how they treat them.
But I say that what we think affects how we act. It’s just basic human nature.
There is no question that this survey reveals their bias. Just another example of “ivory tower” elitism.
