I do see, mostly from Americans, self introductions of the form "I'm so and so... and I love Jesus" in contexts that have nothing to do with religion. I've never had anyone bring up their atheism or agnosticism in that way in a non-religious context.

I've lived/traveled all over the Bible belt and I can't remember that ever happening even once. I'm sure it does happen but never seen it.

Have you ever encountered the atheist version IRL? Not just in internet bickering?

Maybe it was regional - I wouldn't know which region they were from off the cuff.

My family is mostly C of E and I don't recall any of them ever bringing up religious topics with third parties unprompted, so it did strike me as pretty weird.
