"Little distinguishes democracy in America more sharply from Europe than the primacy—and permissiveness—of our commitment to free speech. Yet ongoing controversies at American universities suggest that free speech is becoming a partisan issue.

Free speech for some, they argue, serves only to silence and exclude others. Denying hateful or historically “privileged” voices a platform is thus necessary to make equality effective, so that the marginalized and vulnerable can finally speak up—and be heard."
