In the wake of the horrific Christchurch shootings, we need to engage thoughtfully with the ideology which influenced it. Just before the massacre, the self-confessed killer, Brenton Tarrant, distributed what is being called a manifesto, in which he unashamedly describes what he was about to do as a “terrorist attack”, and gives and account of his ideology. We need to understand this ideology, not to give it a platform, but to learn and to equip ourselves to stand against such hatred.
