The problem isn't where these groups meet; it's what they believe.
We have several of those churches locally. One is a merger of two small churches. Very evangelical and contemporary. They seem to have eschewed politics. The UMC plant is very touchy feely, like a social club. There is a Southern Baptist plant and an RP plant. The Southern Baptist is homey and the RP is very stiff and traditional.
Of course all of them hide their denomination links. The one old-timer, an independent startup, is very conservative and growing rapidly.
