Well I’m glad you agree at last.
I would say the same about a homosexual union. All other things being equal, the (sexual) relationship between a man and woman who are faithful to each other is NOT the same as the (sexual) relationship between a man and a man.
They are obviously different.
Good so far. But here it falls down.
And one isn’t as good as the other. One is broken. The other isn’t.
That’s not a good analogy. In fact, it’s not an analogy at all. The first is a broken relationship. Two people has trust in each other, they promised to be faithful to each other but one of them cheated, and his/her promise and their relationship was broken. There is a reason why we can say it is broken. And as you said:
But a homosexual relationship isn’t broken. It is simply ‘not the same’. The only reason you can give (and you do need a reason) is that it is against Natural Law. And we’re back to God (It’s wrong because it’s wrong because…well, God says so). That’s not acceptable.
Everything wouldn’t be permissible for me. But it would be permissible for anyone else to do any immoral thing he decided to do.
For anyone else but not for
you? How does that work? Are you a better person than everyone else? You’d probably say not. So what would prevent you doing what you wanted? You’d have no Natural Law, no morality ordained by God, no Church to give you guidance, but you’d still be a good person. Which is odd, because if you asked a gazillion Christians would they rape and murder if there were no God, everyone would say – oh no, not me. That would be someone else. Every. Single. One. Because we’d all be seriously concerned if they said otherwise, wouldn’t we (What? Is your belief the only thing that stopping you? No way!)
So all the Christians would be good. All the atheists are already in that position, so we’re all good. So it look like, to me, that nothing would change.
When I say: that’s not the right thing to do!
He would then say: different strokes for different folks. I come to a different conclusion than you do, and there is no ultimate authority save for the almighty self. And I decided that it’s absolutely moral to kill my daughter.
A belief in God doesn’t stop you killing (check out the murder rate in the US versus the percentage Christians) and a lack of belief doesn’t allow you to (as you’ve just explained).
