Free speech is not for the faint of heart.

Nor is it for those who are easily offended, readily intimidated or who need everything wrapped in a neat and tidy bow. Free speech is often messy, foul-mouthed, obscene, intolerant, undignified, insensitive, cantankerous, bawdy and volatile.

While free speech can also be tender, tolerant, soft-spoken, sensitive and sweet, it is free speech's hot-blooded alter ego—the wretched, brutal, beastly Mr. Hyde to its restrained, dignified and civil Dr. Jekyll—that tests the limits of our so-called egalitarian commitment to its broad-minded principles.

Unfortunately, our appreciation for a robust freedom of speech has worn thin over the years.

Many Americans have become fearfully polite, careful to avoid offense, and largely unwilling to be labeled intolerant, hateful, closed-minded or any of the other toxic labels that carry a badge of shame today. We've come to prize civility over freedom. Most of all, too many Americans, held hostage by their screen devices and the talking heads on television, have lost the ability to think critically.
