It probably got started with “Islam is the religion of Peace!”
So every time some moslem killed someone, someone would say the victim was done in by the peaceful “Amish”.
Then feral blacks were deemed “peaceful” and when someone got brutalized everyone started again saying it must have been the “Amish”.
Eventually the name stuck.
Thanks. I am well aware of the history ... but it is getting old. Maybe switch to Quakers. :-)
We would appreciate a return of Tourist Guy.
