In a piece in his weekly newsletter, Murray McCully exposes National's true colours as the party of bigotry by accusing the government of "officially endors[ing]" homosexuality in its "no rubba, no hubba hubba" ads. How? By showing a gay couple in some ads, getting up to exactly what the straight couple get up to in the rest.
McCully seems to find this offensive - not to mention threatening, judging by the number of times he mentions his heterosexuality in such a short piece. And his preferences are quite clear: gays shouldn't be seen on TV, and should get back in the closet with women and Maori, where they belong. It's the sort of attitude you'd expect to see from the bigots in United Future and NZFirst, not from the chief political strategist of a supposedly mainstream party like National, which aspires to represent all New Zealanders. But then, it's clear from their overwhelming opposition to the Civil Union Bill where the majority of National MP's stand - and it isn't on the side of tolerance and diversity.
As for the ad itself, it's not an endorsement - it's a depiction of reality. Gays exist, and (Shock! Horror!) have sex. And that's something that Murray McCully and his ilk are simply going to have to get used to.
