Okay. Thank you for this insight, and also for your honesty.They are separating themselves from the world, the world being anything that isn't Amish in practice. It is a continuously changing complexity of reasoning. As my father-in-law used to say, anything that is highly esteemed among men we choose to avoid, in avoiding we protect ourselves of being proud of what we have or are. In their reasoning automobiles would make it easy for you to go to places that would be destructive to moral human life, such as a bar, strip clubs, beaches etc..... places that they consider immoral and indecent to the overall mental health of the individual.
Avoiding phones is similar in nature. The reasons given not to have a phone in the house is that it could be a distraction having it so close at hand and it would tend to take away from family time. In my experience with them having phones in their little shacks outside it actually gives their young people more opportunity to do or have conversation with their friends on the sly because the shack door is shut and they can't see or hear them inside.
There are major complexities to all the reasoning behind a lot of the reasons given, because they often contradict themselves in practice. Some of them know that, but don't really know how to change it, or, it's just the way it is and it's been this way for all of our lives. We're used to not making sense to others. It's a very pick and choose lifestyle.
Some of the attitude is, that we don't have to make sense to the outsiders, we live how we want to live and they need to be okay with that.
