A Mennonite is a member of a Protestant Christian family of churches that grew out of a 1500s movement which baptised only people old enough to choose for themselves. They take the name from Menno Simons, a leader of the second generation. Classic marks, in the old picture: they will not join the army; historically many would not take public office, because they wanted church and government kept apart; and they do not baptise babies. There are many Mennonite groups, from very plain to quite modern. Learner dictionaries often fold the Amish in; though actually the Amish split off from Swiss Mennonites centuries ago. They are cousins, not the same hat. The people in buggies and old-style clothes that films love are usually Amish. Plenty of Mennonites today drive cars, hold jobs, and live in ordinary towns. They are many in the US, but also in Canada, Latin America, Africa, and elsewhere — not only America. In Taiwan you may already know the name from 門諾醫院 in Hualien, which Mennonite missionaries helped build. Always capitalised, like Catholic or Buddhist, because it names a people and a faith.
