Well, that is daft, because she is discriminating...against anybody that wants to get married !
I don't really understand the Christian nutters on this issue. In the western world, less and less people are getting married these days. When I was young in the 60's, it was looked on with shock and disapproval if you lived together, and had children out of wedlock. Indeed, there was a special word for children born that way.
So you would have thought the Churches would be welcoming people who wanted to get married, instead living together !
