If you set foot on a college campus these days, you’ll be bombarded with feel-good buzzwords intended to convince you of how caring and inclusive the environment is.

The words “tolerance” and “diversity” are drilled into students’ heads from orientation on, but it doesn’t take savvy students long to figure out just how empty those concepts are in academia these days.

The concept of diversity is only skin deep; everyone is welcomed regardless of color or sexual orientation—as long as they don’t deviate from the narrow ideological framework that dominates many college campuses. Diversity of thought—presumably the most important type of diversity in an institution whose purpose is to enrich the mind—is not valued. And tolerance never seems to extend to those who reject the worldview that schools attempt to impose.

Case in point, Columbia University:

Students stormed the stage at Columbia University’s Roone auditorium yesterday, knocking over chairs and tables and attacking Jim Gilchrist, the founder of the Minutemen, a group that patrols the border between America and Mexico.

Mr. Gilchrist and Marvin Stewart, another member of his group, were in the process of giving a speech at the invitation of the Columbia College Republicans. They were escorted off the stage unharmed and exited the auditorium by a back door.

[...]

The student protesters, who attended the event clad in white as a sign of dissent, booed and shouted the speakers down throughout. They interrupted Mr. Stewart, who is African-American, when he referred to the Declaration of Independence’s self-evident truth that “All men are created equal,” calling him a racist, a sellout, and a black white supremacist.

A student’s demand that Mr. Stewart speak in Spanish elicited thundering applause and brought the protesters to their feet. The protesters remained standing, turned their backs on Mr. Stewart for the remainder of his remarks, and drowned him out by chanting, “Wrap it up, wrap it up!” Mr. Stewart appeared unfazed by their behavior. He simply smiled and bellowed, “No wonder you don’t know what you’re talking about.”

“These are racist individuals heading a project that terrorizes immigrants on the U.S.-Mexican border,” Ryan Fukumori, a Columbia junior who took part in the protest, told The New York Sun. “They have no right to be able to speak here.”

As of now, the Columbia administration has taken absolutely no disciplinary action launched an investigation.

If it infuriates you to read this, then you may want to be sure you’ve taken your medications before watching the video.

Update: Columbia University president Lee Bollinger released a statement on the incident, which I’ve excerpted:

The disruption on Wednesday night that resulted in the termination of an event organized by the Columbia College Republicans in Lerner Hall represents, in my judgment, one of the most serious breaches of academic faith that can occur in a university such as ours.

Of course, the University is thoroughly investigating the incident, and it is critically important not to prejudge the outcome of that inquiry with respect to individuals. But, as we made clear in our University statements on both Wednesday night and Thursday, we must speak out to deplore a disruption that threatens the central principle to which we are institutionally dedicated, namely to respect the rights of others to express their views.

This is not complicated: Students and faculty have rights to invite speakers to the campus. Others have rights to hear them. Those who wish to protest have rights to do so. No one, however, shall have the right or the power to use the cover of protest to silence speakers. This is a sacrosanct and inviolable principle.

It is unacceptable to seek to deprive another person of his or her right of expression through actions such as taking a stage and interrupting the speech. We rightly have a visceral rejection of this behavior, because we all sense how easy it is to slide from our collective commitment to the hard work of intellectual confrontation to the easy path of physical brutishness. When the latter happens, we know instinctively we are all threatened.

These are reassuring words. And I hope Mr. Bollinger intends to stand by them and see that the principles therein are enforced at Columbia. I’ll believe it when I see it, though; Columbia doesn’t exactly have a stellar reputation when it comes to these politically-charged investigations.
