There are groups of conservative/traditional people who think they can insulate themselves from the secular world, and save themselves and their families from the bad influences. While I admire their efforts, as long as human nature is weak, there will be sin. If such people are Christian, I think they run the risk of ignoring Our Lord's commission to spread the Gospel to the four corners of the earth.
The Amish and Mennonite plain people know a lot about sin and pain. I remember well the Plain Dress Mennonite woman who stayed with me a week. Her face was a criss cross of the scars she bore after an attack on the African mission she helped found.
I visited a middle TN Mennonnite community and learned of their mission work in Europe. At times, I envy the peace they appear to have in life. I'm very sorry this tragedy touched them.
I think the Amish people can pull together through the pain and they may actually help us a little rather than the other way around.
The hunanistic world has its "grief counselors" etc. but God's love as poured out through human beings is a much more powerful force.
"Loving God and loving your neighbor as yourself" has power when and where it is practiced.
I'm optimistic for the future of the Amish and hope the rest of us will pick up something along the way.
I'm not a legalistic pacifist so I'm not praising all about Anabaptists, but there is something for us to consider in how they respond to all of this.
