Amen to that. Even if you do not share their faith, the extent to which they are willing to adhere to such, in the face of such an insane, random incident, should be a point of reflection for all.
Yup. They are an example of what is best about Christianity. Most religions offer some group of believers who epitomize the core values of that religion, at least from my own experience.
The Amish, along with other of the "simple" sects of Christianity, seem to me to do that for Christianity. There are some orders of monks and nuns of Catholicism who do something very similar in following Jesus' teachings. Some offer retreats where a guy can visit for a period. Very worthwhile.
I know a monastery of Buddhists that seems to me to epitomize the core of Buddhism, as well, and have retreated there a couple of times.
I've also done a retreat at a Hindu retreat center which has about it the same simple faith.
It's terrific to see such people in real life.
