Do the bishops seriously imagine that legalising gay marriage will result in thousands of parties to heterosexual marriages suddenly deciding to get divorced so they can marry a person of the same sex?

This is a very tough business, politics. It's easy to get resentful or full of bitterness ... (but) I think hatred hurts the hater more than the hated. So I'm looking back on my time positively.

Newspapers are busily experimenting with different models. Traditionally, and I suspect in hindsight very mistakenly, online news was free. And once given free access readers felt it was their entitlement.
