New Zealand's Prime Minister Jacinda Ardern adopted a novel but effective approach to talking about the terror threat.

In a speech before the parliament on March 19, she said that she would never speak the name of the 28-year-old Australian man charged with opening fire at two mosques which killed 50 people last week.

Visibility supports the spread of terror. It makes terrorists look more important than they really are, giving them a platform to spread their message. He's a terrorist and needs to be viewed as one. What he did was beyond humanity and saying out his name, in a way, humanizes him.

Twitter lauded her decision to refuse giving notoriety to the shooter.

This is the kind of decorum and poise which every world leader needs to have.
