Punishing people for their words does not make the words vanish from memory. The unsayable is not unthinkable. Indeed, the punishment of the word may actually magnify the impact of the thought. Never mind abstract free-speech principles: Purely on pragmatic grounds, when a member of a community says something that bitterly divides the community, the way to a resolution is not to suppress the thought, but to argue it out.
~ David Frum via The Atlantic
