Non-violence
The Amish are famously very pacifist when it comes to violence. You'll rarely find an Amish member supporting the military. Their religious beliefs forbid any violent acts, especially war.
Faceless Dolls
Have you ever seen an Amish doll? Locals right outside of the Amish community are probably more likely to have seen these dolls, but these are very popular for Amish children. The dolls are faceless because the Amish do not like to promote pride and vanity.
