I don't think I pointed this out in the Discord server, but one thing that frustrates me most about this map is Cook County being labeled as "Other". What is this mystery denomination of one of the most populous counties in the country?
Which Discord server is this one?
The distribution of the American Baptist Convention is rather interesting, with some areas of strength in West Virginia as well as Maine. Providence County having ABC as the largest Protestant denomination is a nice touch and reminder of Rhode Island's Baptist heritage.
Speaking of West Virginia, I'm surprised only one county there has the Southern Baptists as the largest denomination. I wonder if this is a result of the Civil War or something else.
