Editor's note

Kia ora tatou and welcome to this week’s newsletter.

This week, Massey University lecturer in human development Cat Pausé responds to a call by the British Psychological Society that we should change how we talk about fatness and no longer use the phrase “obese people”, but instead, “people with obesity” or “people living with obesity”. She argues that the proposed language change assumes that obesity is a disease to be cured, which in turn only serves to reinforce stigma, rather than prevent it.

AUT law expert Alexander Gillespie explores the second phase of gun law reforms, following the Christchurch mosque shootings on 15 March. This part of the process includes setting up a register for all firearms, which would be the third time in recent history New Zealand has attempted to reintroduce one.

The character of Judge Dredd was first introduced in 1977, in the second issue of the comic 2000AD. His creators envisioned the character as a no-nonsense cop - “a psycho character with no feelings”. The Dredd comics were designed to be satirical, but AUT lecturer in popular culture Justin Matthews writes that the parallels with contemporary society appear uncanny and symbolise the demise of democracy and freedom in favour of authoritarian regimes.

And this week’s Climate Explained explores the carbon and environmental footprint of electric cars.

Many thanks for reading. Feel free to share this newsletter - or any other stories on the New Zealand page - with friends and colleagues who may be interested. Ka kite anō au ki a koutou.
