Sort of my take also (I a Lutheran BTW). Probably a great place to raise kids, but we are called to be a light to the world.
But at the same time a movement like this COULD be a light. A view of a way of life that is unlike what you can see in most US towns.
Well, and I mean this with all due respect, we certainly have not done much lighting in this world have we? So, perhaps this is another way of showing Gods goodness?
