re: Only in a one-religion town.
Just because you somehow wound up in some kind of religious crackpot vortex doesn't mean that your situation applies everywhere.
I've never even heard of that first looney statement. Do you hear it a lot where you are?
I have a large extended family that, for many generations, has found comfort and community in their Midwestern churches, of which there were usually several denominations in even the smallest towns, and there weren't ANY of them who were mumbling about Catholics taking over America.
Maybe you need to get away from home more.
