"Amish" is a word used to describe a variety of different Mennonite Anabaptist groups.
There are Old Order, New Order, Beachy, Schwartzenruberite and others. These beardcutters may simply be a new group.
Just because the Amish generally profess antimilitarism does not mean that they are above sectarian violence, which has a rich tradition among Anabaptists.
I’m an Anabaptist ... you’re wrong.
