The American Association of University Professors has documented more than 100 incidents of harassment—including death threats—targeting college professors for expressing viewpoints that included Trump criticisms while in the classroom. According to CNN, some of the professors have been forced to teach remotely via video conference:

-- A California professor at Orange Coast College who was captured on video in the classroom criticizing President Donald Trump got death threats, according to The Washington Post. -- CBS News reported a Princeton professor received death threats after giving a commencement speech in which she called Trump a "racist and sexist megalomaniac." -- A University of Iowa professor was targeted after discussing white supremacy in the context of ancient statues and their use of white marble, InsideHigherEd.com says.

"There's an entire cottage industry for reporting on controversial things that faculty members say,” said Ari Cohn of the Foundation for Individual Rights in Education, “which then riles up Internet outrage mobs, who then start to tweet at schools, or post on Facebook, and try to get schools to get rid of people who they disagree with.” Among those riling up those mobs is a right-wing activist that Trump praised on Twitter:

One of the websites, called Professor Watchlist, was started by Charlie Kirk. "Our goal is to expose and really profile professors that have engaged in outward radical behavior," said Kirk. "We're not saying these professors should be silenced. Instead, we're pointing out what has become a systemic problem in our universities, where professors are able to say things that are completely outrageous." When it comes to the harassment and death threats that professors face, Kirk says it's not his website but the professors themselves who bear responsibility for the consequences of their words. "We do not call for any that sort of harassment. We don't condone it, we don't try to facilitate any sort of cyberbullying or harassment, and just because you put up the words, or another article that's been written about a professor in an aggregated format, does not mean we should be held responsible for what other people do."

Right, no facilitating done here, other than allowing people to search for professors by name or school and then washing their hands clean of them from there. “What we are seeing with this site is a kind of normalizing of prosecuting professors, shaming professors, defaming professors,” Julio Pino, an associate professor of history at Kent State University told the New York Times last year.
