Almost exactly five years ago, I called your attention here to a brouhaha in the small town of Kanab, Utah, over the adoption by the city council of a non-binding resolution defining the family as "one man, one woman" with a "full quiver" of children. A few months later, Laura and I visited Kanab (a town founded by Mormon polygamists), where we were pleased to see many businesses opposing the resolution with "Everyone Welcome Here!" stickers in their windows.
I wish I'd known sooner, but I've just learned that there's a documentary out about the whole controversy:
I can't vouch for the quality, not having seen it yet, but you can be sure I'm ordering a copy and will watch it with interest.
