Medicine is perhaps the most technically advanced progress in all of human civilization.
If they restricted themselves to 1830 technology in medicine like trains they'd have a life expectancy of 45 (had to double-check that, yup 45)
Utter hypocrisy.
They can still live a simple life if they want even with technology. I feel like I do that every day. I don't even use a cellphone.
Oh that's another thing, they use cellphones for business. They keep them in sheds out of their house and check them weekly for orders and other work stuff.
Everything is a loophole with these kinds of religions except freedom for women and other diversity.
