OK ... what did you just read?
Are the Amish a cast off religion? (fellow)
Did some that perhaps have been disciplined take revenge?
If the "cast-off" did this deed, then they are not Amish, thus .. the title should be, independent religious liberty attacked by satanic mob.
"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.
