Well I am known to be a Christian and was subjected to all sorts of ridiculous rule making, meetings, and memos before anyone bothered to ask me if I would refuse service to same sex couples. I recognize that there are a lot of teachings that work beautiully on an individual level that would be a disaster if you tried to codify them.
This law is not a thou must, it is a thou mayest.
In other words, these are issues for clergy, etc. to hash out if they must, and ultimately it is about individual conscience towards God. The thing I might believe sinful to get involved with in a certain way, you might not believe sinful. And fine, I wish you well in your walk with God.
It is weird how the diversity folks quail when the issue comes down to diversity of association.
