Whoever they are the owner/s of this site sure appear to have some issues with New Zealand culture. Here's a delightful sample -
"The families of NZ soldiers serving in Afghanistan should be asking, "Is it worth your sons', your husbands', your uncles', and your cousins' lives - to have them risking everything, just because a couple of NZ's top lesbians were blackmailed over their lesbian "threesome" with a butch American lesbian in Washington?" Yeah, that is how NZ's foreign policy was really decided! It wasn't national or strategic interests."
