Nearly everyone knows that the Amish are known for being extremely peaceful. Calling people from a violent culture the "Amish" is what is known as "irony". This is not "wrong, extremely misleading and stupid". Not recognizing "irony" when it is used... makes the clueless person seem feebleminded.
Or principled and not a foolish person. Go ahead and show your ignorance and immaturity by slandering the Amish.
