As a scholar who has researched and written quite a bit about the Anabaptists, can we set a few things straight?
1. Baptists are not Anabaptists. Their history is theirs; ours is ours. We have similarities, but we are not them. We honor them by not using them for our purposes.
2. Not all Anabaptists were in Münster, and many if not most Anabaptists at the time were just as appalled as we are by the Münsterites. So please drop the tropes equating all Anabaptists with Münster. Informed and honest scholars are known by their right retelling of history.
3. The same truth applies to the other types of Reformation Radicals. There is a great difference between those who have become known as Evangelical Anabaptists on the one hand and Spiritualists, Rationalists, etc. on the other hand. Respect them as you also wish to be respected.
4. Yes, there were Anabaptists who toyed with various heresies, including Arianism, Socinianism, and Celestial Flesh Christology. But there were also many Anabaptists who affirmed, commented upon, and used the traditional Apostles’ Creed, Nicene Creed, and Athanasian Creed.
And if you want to do the honest research, you can also find a few heretical Roman Catholic Popes and more than a few heretical Anglicans, Presbyterians, Lutherans. and whomever else you want to talk about. Good historical theology doesn’t play favorites; it speaks the truth.
