With so many 'coming out' stories about atheism, I was wondering if there is a way that atheists can identify one another without asking. In the gay world, it's 'gaydar' - noting the way that someone walks, talks, dresses, interacts with others, or somehow just "is".
I've had a few people, out of the blue (at work) volunteer to me that they are atheist. I didn't ask why, it just seemed like a topic for conversation at the time. Even though it's a very busy workplace and we don't chat much at all.
So I'm wondering, if there is a atheist version of 'gaydar'? Something that makes us think "that person looks like an atheist!". Maybe it's a lack of interest in Xmas, or that is the only person who never mentions going to church, or... what? Seeing that evolve-fish on their car - well, that's obvious. There must be something more subtle.
I've seen a similar situation with Mormons here. Fairly quickly, they seem to identify one another by mentions of their son on a mission, or their trip to Salt Lake City, or, I don't know, their most recent jello recipes. Key words, or key concepts, and maybe mannerisms, seem to help some like-minded people identify one another.
If there is such a 'early detection system', what is it called? Or what should it be called? Somehow 'heathenar' doesn't have that snappy sound.
