The thing though is that “hard line evangelical” doesn’t always equal rural.
I think you’d be surprised how many evangelicals live in fairly populous areas.
Also, I imagine that this has to be a “community/parental supported” issue. Speaking as a Dad, if an adult male showed up at my house to take my “middle teen” daughter out (luckily this is not something I have to worry about for another decade or so), I’d be having a stern talk about police and restraining orders, or long drives out into the remote part of the desert, if I even heard that said adult/predator even looked sideways at my kid.
What I don’t get is why people are so f-ing entranced with the idea “oh, but this is how it was done in biblical times!!!” So F-ing what? They also didn’t have modern medicine or technology, but I bet you’d go to a doctor if needed, and enjoy using your cell phone and car.
