In the aftermath of an atrocity as horrifying as the Paris murders on Wednesday, it is more important than ever to be crystal clear about the freedoms that we hold most dearly. Freedom of expression, which must always include the freedom to offend and to ridicule. Satire is an essential part of a democracy. Incitement to hatred and to violence are crimes; incitement to mockery is not... Freedom from fear, including the fear of being different, or of speaking out, or of questioning majority beliefs. Above all, the freedom from the fear of being murdered.
