As a New Zealander, I'm very proud to live in such a progressive nation.
I find it incredibly sad that purported feminists think that being big, or wearing frilly pink scarves make someone any less of a woman. But to take your point about being convinced, or otherwise, by the photograph, I thought the article was balanced, informative, and didn't attempt to convince the reader of anything. Was I missing something?
Coincidentally, I was glad to see comments disabled. The Stuff comments section can be a bit of a cesspool, and they often leave them enabled on articles with the potential for controversy. Presumably to act as click-bait.
