I hope these Christians do the same study for every other "Christian-majority" countries. That would be a great help to people just wanting a peaceful place to live in and raise a family. I mean, having to deal with nutjobs (regardless of religiousity or the lack of) on a regular basis cause undue stress and can cut off your remaining years.
Though it might alienate people more from each other if they just live near people with similar beliefs and ideology, I'd rather have that than be in a community where you'd have constant race/religious/ethnic tensions.
Surprised to see San Francisco in that list. With the huge Hispanic population there, I was thinking that Catholics would be a majority in that city. Also, there are a lot of Pentecostal and evangelical Christians from the former USSR living there.
Also happens to be the epicenter of seismic, I mean homosexual activity in the West Coast.
