The human instinct to censor thrives, as it always will, living in
irrepressible conflict with the human instinct to speak. Outrage,
self-righteousness, and paranoia feed the maw of censorship.
Squelching speech, however, never reduces society's net paranoia
quotient; it simply redirects it, drives it underground, where it
festers into more dangerous hysterias. In the words of Justice
Brandeis, "Men feared witches and burned women."
