In my experience most people here are a bit nonplussed by all the gender changes, and find the whole thing a bit tedious. But they aren't up in arms about it. In my workplace that is because there's no benefit in putting your head above the parapet. We all have livings to make.
There is also an instinctive dislike of people coming here and telling us what to do, regardless of what they've got to say, and there is also a dislike of being bombastic. Some of that will be driving the comments.
There is a tendency among people in the UK to regard NZ as backward. I have to say that remarks like that cause annoyance, especially as NZ has historically been ahead of the game in social reforms.
Outside Wellington it's actually quite a conservative place. Wellington, though, is a clapboard Brighton. I wouldn't be surprised if Parker was told by the police that if she spoke there, there would be significant disorder with people being harmed, and the reality is that the police here don't have much experience of dealing with things like that. I wouldn't even be surprised to discover that Parker was told that the government might revoke her visa.
