Perhaps you don't actually know why they do the things they do. I had a long conversation with a wonderful Amish man while we were both on vacation in Florida last year. I learned a lot, and became hard-pressed to disagree with many of his view points.
Their shunning of modern equipment does not stem from regarding it as evil. Many of them use power tools, welding machinery and so on. It is mostly communications equipment that they shun. They prefer to converse with their families in person, which contrasts sharply with the families I see texting with others when gathered at restaurants. They object to the TV robbing families of quality time together, or bringing normalcy to immoral practice into their homes in the form of modern sitcoms.
Different groups ban different things as chosen by their elders. They do practice self rule, and believe that most Americans are slaved to government rules that are immoral or just plain thoughtless.
His family was, in general, completely unaware of current events.
Truthfully, I felt a bit envious of their innocence and lack of unawareness of how cruel and heartless life in this Nation has become.
Some of the Amish in our county (there are 3 communities) have a huge breakfast every year and donate all the money to the local fire departments, some of which are volunteer. Last fall, a local fire in a home took the wife and one small child. The fire was on a Tuesday. By the week end the house had been rebuilt from the ground up, and the family moved back. They are okay people.
