Probably the biggest misunderstanding about the Mennonite (and the Amish) is in thinking them each one singular entity.
First, both are broken into Old Order (the ones in black buttonless garb, driving a horse-drawn buggy, just like in “Witness”) and the New Order (with not that different a visible lifestyle from yourself).
Since one basic tenant of Anabaptist (Mennonite, Amish, & Hutterite) belief is the disavowel of a central religious authority (like a Pope) their churches are fraught with schisms — in many cases, over acceptance or rejection of modern trends.
Still throughout these schisms and disagreements on dogma, they have managed to maintain civil discourse between the churches, and combine efforts for religious publishing, education, and especially emergency relief work through their Mennonite Central Committee. (One of Canada’s first civilian organizations reported to be responding to the recent Hurricane Katrina crisis.)
What I find most appealing about the Mennonite faithful as they interact with non-believers, is that, with the exception of the usual missionary work in poverty areas around the world, they do not tend to prostylizes their beliefs.
I live where Mennonites are rather thick on the ground, and they have never tried to coerce me to accept their beliefs.
At least, I suppose I should add, they don't outside their church functions.
