Intersting idea, since the Anabaptist predate the Amish by about 100 years.

Yes, but the Amish believe they are the purist form of Anabaptist. They believe that all other Anabaptist groups are far afield from doctrines and precepts that are truly Anabaptist and that they alone know, understand and practice true Anabaptism.
In fact, among themselves, they say that no other group is even really truly Christian. They believe the logical conclusion to a true understanding of the Bible is to live like they do.
My aunt was mortally injured in a car-pedestrian accident. She was in the hospital for a few days before she died, and by some twist of administration, she was put in the same room as the woman who was driving the car that hit her, who had ht a pole after hitting my aunt. The woman who hit her was Beachy, and my aunt was Amish. My aunt was fully clothed in Amish nightwear, with her headcovering and a shawl over her shoulders to protect her modesty. The woman who hit her took off her headcovering and wore a hospital nightgown, no shawl or anything other than covers to protect her modesty. And she cried when the drugs wore off and she felt pain.
At my aunt's funeral, the pastor, my uncle, preached on the evils of being anything but Amish. He called the Beachy woman a harlot and said she might as well be Catholic as Amish. The Amish believe Catholicism is the embodiment of evil, and with every new pope, someone preaches a sermon or writes a pamphlet about how this pope is going to turn out to be the antichrist.
But back to my story. The preacher said that my aunt, dying as she was, stayed faithful to the one true faith, Amish, and that the Beachy woman, for all their plain-dressing, show themselves to be reprobates when they are put to the test by suffering. When she allowed herself to be "uncovered" in the hospital, she might as well have been naked and without proper Amish garb and lifestyle, no one can hope to please the Lord unto salvation. And when she cried in pain, she was showing that God was punishing her for her wicked lifestyle.
He said that no one can be saved outside the Amish church, and that Beachys and other plain people are pretenders, people who wish they were Amish but are unwilling to separate themselves from the world as they properly ought. And by doing so, they miss out on salvation.
Maybe that's just one pastor's opinion, but I have read several booklets my parents had about the evils of the world and how to live in the world is to make alliance with Satan and to kill any hopes of seeing paradise.
Whatever else the Amish believe, they do not believe you or anyone outside their communities, to be their true brethren in Christ, even me if I never return.
