Great stuff from Chrys Stevenson! Follow the links and you'll see what utter sanctimonious claptrap the Catholic bishops have produced in arguing against provision for same-sex marriage.
You know, I'm not even someone who cares all that strongly about the issue of same-sex marriage; maybe I would if I were gay, but even a lot of gay people don't feel that strongly. But there is simply no good secular argument against it. It shouldn't be a huge issue, but merely a natural social development. In current social circumstances, the rational and realistic policy option is to provide for same-sex marriages on terms closely analogous to those applying to opposite-sex marriages (mainly this: if you want to involve more than two people, the state won't recognise it, and you'll have to do so unofficially).
The attempts by the bishops to offer secular arguments against same-sex marriage are embarrassing. And you'll see that they can't resist also putting theological reasons, relating to God's plans, in the mix.
Now, bishops have freedom of speech like everyone else. I don't want to silence by force of law. Indeed, I'd allow more speech than is currently allowed by our laws, and this pastoral letter is fine at that level. Let the bishops express themselves and get all this stuff off their chests.
But freedom of speech is not a positive right to have your speech taken seriously or treated with respect. The Catholic bishops' pastoral is precisely the sort of speech that deserves mockery and social marginalisation. That's how we ought to respond.
