Disa
I've seldom encountered it (my wife's fundamentalist sisters go after her and know enough to leave me alone). But I understand there are places in the rural US "Bible Belt" where it's the first thing out of new neighbors' mouths when they come around to visit.
It's not just rural. As a kid starting fourth grade in a city in Georgia I was asked what religion I was right off the bat. When I said I don't think I'm any religion the other kids promptly informed me I was going straight to hell. This is a common occurrence even in Metro Atlanta today. We aren't at all rural, with a huge diverse population, and my daughter experienced the same thing when she was in school. Frankly it makes me sick. I grew up thinking something was wrong with me due to all the fire and brimstone bible thumpers around condemning me to hell. When it happened to my daughter around the age of seven, I took her to a church of Christ for one full year so that she could see what it was and decide if it was for her. I went with her twice per week for an entire year. It isn't for us.
These days I don't discuss it at all unless someone else brings it up. Then I'm spiritual and not religious. The reactions are not much better from adults than they were from children. I'm always interested in listening to the beliefs of others, but others do not show the same degree of compassion,respect, or interest.
I like the one about how I'm a spirit having a human experience, not a human having a spiritual experience. Or words to that effect, anyway.
This is the basic premise of all my metaphysical courses. I agree with it, so the courses all resonated.
