Re: #75
Here is an article about segregation and diversity in churches, and how worshipers and pastors see it:

(Again, not South-specific.)
Arab people include members of many religions, including both Sunni and Shia Islam, various kinds of Christianity (e.g. Orthodox, Catholic, Copt), Druze, and Bahai. There are also people who describe themselves as Arab Jewish, though there is some controversy over the term.
According to https://web.archive.org/web/20060601221810/http://www.aaiusa.org/arab-americans/22/demographics , most Arab American people are Christian, and only about a quarter are Muslim.
