Neither do most Anglicans.
This is their POV.

Being " of the world" most of us would just be ignored.
I'm more interested in what we could practically do?
Probably most of us don't even go, even to be a voice in the background.
I'm inclined to think as long as the law of the land is fair and doesn't discriminate the battles won.
But I suppose it doesn't take into account gay Christians who get hurt by it.
Part of me thinks you won't change them ( the people in the church making the decision) by disapproving because the bible says the world morally will go to pot.......and people will fall away from the church. ( scoffers and all that)
So provided the law stays fair towards gay people, I'm inclined to leave be.
You can't really dictate to a followers of a religion what to think, from outside, they have to get there on their own.
The most we can do is to protect common law so it protects gay people regardless of what a religious group thinks.
Obviously if we have freedom of thought it opens it up to thoughts we don't like.
