The over the top criticism of Obama and the glowing support for Trump just doesn't sound like a Kiwi to me.
FWIW, I have a brother who's been living in the USA for over 5 years. He was as Kiwi as me before he left. Late last year he was here, and in conversation I threw in some off-hand comment about what an idiot Trump is and how he didn't have a chance. Well, my brother came back an endorsement of Trump, although not as B&W as the quote this refers to! I was astounded. I think he would vote for Trump if he gets the chance. Apart from this, he seemed sane and rational.
Dunno what this says about my brother, Kiwi expats in the USA, or Trump. But it's just a data point that says that their may be a Kiwi somewhere who believes all that stuff.
