When Is Free Speech Hate Speech? [PDF ebook] 

Free speech is guaranteed under the First Amendment. Although it may hurt and offend, hate speech is still free, under most circumstances. But what happens when institutions like universities adopt policies prohibiting offensive speech? Do such policies cause more harm than good? Should measures be taken to curb threatening or insulting comments? Or does that amount to little more than censorship? Is our quest to be polite and politically correct curtailing opportunities to express, learn, and grow? When does free speech become criminally threatening? These questions and more are thoughtfully examined in this important resource.
