Yes I'll go along with that.
However, are those Christians the exception as opposed to the rule?
What about the "death to gays" schtick in the OT? Do these liberal Christians condemn that mindset or do they defend it?
Obviously, they don't defend it. I think there are all kinds of attitudes to the Jewish Bible, for example, some liberals see it in a historical context, and therefore outmoded today.
But in the C of E today, you have the strange position, that the church itself is officially homophobic, and seem to have joined in with the suspension of the American church, yet many members are gay-friendly. For example, I used to go to a church where the rector himself was gay, and had a very obvious boy-friend. I think the bishop disapproved, but the church itself was packed to the rafters.
From memory, the majority of US Catholics support gay marriage, and in fact, more than in the general population.
