Most people would expect this post to be a negative one - but I genuinely do wish the Queen a happy 90th birthday.
As I've long argued, the Queen is our head of State, yet the head of State issue in New Zealand is not actually about the Queen or the Royals generally. If New Zealand had a head of State of its own, the Royals would still be around and in our media. That would be the case even if Britain became a republic. So there's no reason to be mean-spirited on birthdays or other family events. Happy birthday Your Majesty.
