The progressive ideas behind the lack of free speech on campus

'Is an academic discussion of free speech potentially traumatic? A recent panel for Smith College alumnae aimed at “challenging the ideological echo chamber” elicited this ominous “trigger/content warning” when a transcript appeared in the campus newspaper: “Racism/racial slurs, ableist slurs, antisemitic language, anti-Muslim/Islamophobic language, anti-immigrant language, sexist/misogynistic slurs, references to race-based violence, references to antisemitic violence.”

No one on this panel, in which I participated, trafficked in slurs. So what prompted the warning?

... These days, when students talk about threats to their safety and demand access to “safe spaces,” they’re often talking about the threat of unwelcome speech and demanding protection from the emotional disturbances sparked by unsettling ideas. It’s not just rape that some women on campus fear: It’s discussions of rape. At Brown University, a scheduled debate between two feminists about rape culture was criticized for, as the Brown Daily Herald put it, undermining “the University’s mission to create a safe and supportive environment for survivors.” In a school-wide e-mail, Brown President Christina Paxon emphasized her belief in the existence of rape culture and invited students to an alternative lecture, to be given at the same time as the debate. And the Daily Herald reported that students who feared being “attacked by the viewpoints” offered at the debate could instead “find a safe space” among “sexual assault peer educators, women peer counselors and staff” during the same time slot. Presumably they all shared the same viewpoints and could be trusted not to “attack” anyone with their ideas.

You can credit — or blame — progressives for this enthusiastic embrace of censorship. It reflects, in part, the influence of three popular movements dating back decades: the feminist anti-porn crusades, the pop-psychology recovery movement and the emergence of multiculturalism on college campuses.

In the 1980s, law professor Catharine MacKinnon and writer Andrea Dworkin showed the way, popularizing a view of free speech as a barrier to equality. These two impassioned feminists framed pornography — its production, distribution and consumption — as an assault on women. They devised a novel definition of pornography as a violation of women’s civil rights, and championed a model anti-porn ordinance that would authorize civil actions by any woman “aggrieved” by pornography. In 1984, the city of Indianapolis adopted the measure, defining pornography as a “discriminatory practice,” but it was quickly struck down in federal court as unconstitutional. “Indianapolis justifies the ordinance on the ground that pornography affects thoughts,” the court noted. “This is thought control.”'
