That is the context into which Dr. Murray walked and was so profoundly misunderstood.

From the stage where I sat with Dr. Murray, waiting for students to take their seats, I saw a sea of humanity. Students were chanting, “Who is the enemy? White supremacy,” and “Racist, sexist, anti-gay: Charles Murray, go away!” Others were yelling obscenities at Dr. Murray or one another. What alarmed me most, however, was what I saw in the eyes of the crowd. Those who wanted the event to take place made eye contact with me. Those intent on disrupting it steadfastly refused to do so. They couldn’t look at me directly, because if they had, they would have seen another human being.

The protesters succeeded in shutting down the lecture. We were forced to move to another site and broadcast our discussion via live stream, while activists who had figured out where we were banged on the windows and set off fire alarms. Afterward, as Dr. Murray and I left the building with Bill Burger, Middlebury’s vice president for communications, a mob charged us.

Most of the hatred was focused on Dr. Murray, but when I took his right arm to shield him and to make sure we stayed together, the crowd turned on me. Someone pulled my hair, while others were shoving me. I feared for my life. Once we got into the car, protesters climbed on it, hitting the windows and rocking the vehicle whenever we stopped to avoid harming them. I am still wearing a neck brace, and spent a week in a dark room to recover from a concussion caused by the whiplash.

It is obvious that some protesters made dangerous choices. But with time to reflect, I have to say that I hear and understand the righteous anger of many of those who shouted us down. I know that many students felt they were standing up to protect marginalized people who have been demeaned or even threatened under the guise of free speech.

But for us to engage with one another as fellow human beings — even on issues where we passionately disagree — we need reason, not just emotions. Middlebury students could have learned from identifying flawed assumptions or logical shortcomings in Dr. Murray’s arguments. They could have challenged him in the Q. and A. If the ways in which his misinterpreted ideas have been weaponized precluded hearing him out, students also had the option of protesting outside, walking out of the talk or simply refusing to attend.
