Marriage Down Under
People on the anti-marriage side often get worked up over the term "homophobia," since taken literally it implies that opposition to equal treatment for homosexuality is rooted in visceral revulsion, rather than a principled stance. But looking at the arguments from Labor's right wingers, it's clear that in this case "homophobia" is a quite apt term. They are against registered partnerships because they would "demean" and "attack" opposite-sex marriage and "robs marriage of its unique and privileged status." The only way that expanding access to a right or status can "demean" the people who already had it is if those people think "eww, I don't want to be in the same category as those people."
On the other hand, another argument made by Labor's right would be better described as "homo-callous," though it rests on the electorate's homophobia. I mean here the US-Democrat-style argument that rights for same-sex couples have to be sacrificed to the all-important goal of getting elected.
