A controversial op-ed published in the New York Times earlier this month argued that it was reasonable for universities to ban lectures by speakers such as Milo Yiannopoulos on the grounds that certain speech can constitute violence. Author Lisa Feldman Barrett, a professor of psychology at Northeastern University, sought to provide substantive weight to a refrain used increasingly by liberal campus activists in their attempts to censor controversial speakers, most of whom happen to be right-of-center.

In that respect, her op-ed was a welcome contribution to the discussion, since these activists rarely appear capable of offering substantive defenses of this contention, which is key to their pleas for censorship.
