Only one way to find out.
I'm not normally an advocate for violence, but calling for a peaceful resolution and compromise with a person who wants to eradicate people from existence is idiotic.
A person calling for violence against others invites violence against himself.
That's really not true either. They don't take issue with technology.
They have cell phones and washing machines. Some Amish communities just look like any old country highway with pickup trucks and harvesting equipment.
The particular type of Amish you're thinking of will still have things like landlines and probably some electricity on the farm.
They take issue with depending on others, Amish strive to be self sufficient and independent. They don't want to attach themselves to possessions, or things they can't make and maintain themselves, but that doesn't mean they can't use them. They can and gladly do. They have rules on their use, they self regulate their use. Guy I went to school with has his wife go through and look through his phone. If she thought the was using it too much she'd hang on to it. He drove an old pickup and he and his brothers ran a junk yard part time specifically so he'd have access to parts for it. He was going to school to be a machinist, because there was a machine shop in his community and he didn't want to bother the elders with learning how to use it. Soon as he finished the precision machine program he just went back to his farm.
