Ok well
I don't think that the Genesis story can really be married up with science these days but I don't think that is such a problem either - people at the time people wanted answers but could never have understood the physics of the origins of the universe so God gave them a story that still encapsulated the big stuff - that we are made in Gods image (however you want to interpret that), that we have a tendency to want to use our free will for the wrong reasons, that God desires a relationship with us.
The gay issue is a bigger one - I don't think the Bible condemns monogamous Gay relationships anywhere. In Biblical times there was no concept of 'homosexuality' as we know it today. It was believed that everyone was naturally straight, but some occasionally deviated from this in the pursuit of lust. We know now, though, that gay people desire the same commitment, romance, trust, security and love that heterosexual people do. I've been lucky enough to know lots of gay people who I could bounce questions off, and from them I have been convinced that you are born gay - it doesn't come from an absent or domineering parent, or any other external influence. So why would God create you in such a way if it was such an abomination? I think ex-gay ministry works sometimes - I think young people can sometimes be confused when their sexuality awakens as they go through puberty, and I don't doubt that many people have been helped. But ex-gay ministry has claimed a lot of victims too - there are lots of stories of people going into a marriage, only to leave it, or worse, commit suicide, a few years down the track because they feel as though they have tried to force themselves into being something they're not. So I've come to that conclusion through what I've read of biblical scholarship but also, more importantly, through my life experience (you really would be suprised at just how many gay people I have become friends with in my life - one of the benefits of working in the arts
)
As for abortion, I think its an absolute tragedy, but if its made illegal then it leads to girls who feel they have no choice having it done illegally in someone's backyard in awful circumstances - how much better would it be if they had somewhere safe they could go, where they could get counselling as well?
