The law was a combination of utopian strategy and fascist tactics, as many attempts to re-engineer human beings are. It regulated human emotions. Section 13 made it illegal to publish anything on the Internet “likely to expose a person … to hatred or contempt.”
But hatred and contempt are natural human feelings. You can no more ban hate than you can ban love; if it were possible, we would have passed the Love Each Other Act long ago. It’s not possible. And it’s not desirable.
