This new trend is driven by a belief that evil words sooner or later will lead to evil deeds, and that there is no principle difference between the two. This sounds to me like dangerous logic, popular among fanatics who equate blasphemy and terror, who identify critical words with violent actions. It is widespread in countries like Pakistan, Iran and Saudi Arabia, where both terror and blasphemy are crimes punishable by death.
But the only right we do not and should not have in a liberal democracy is a right not to be offended. Instead of sending people to sensitivity training when they say something insensitive, we all need insensitivity training. We all need thicker skins if freedom of speech is to survive in the age of grievance fundamentalism.
