From what I understand of the various sects, Protestants are those Western groups who have broken away either directly from the Catholic Church, or from those who broke from the Catholic Church or who broke from those who broke from those who broke from The Church, or etc. AND maintain some idea of Apostolic Succession, Trinitarianism etc.

Baptists are "evangelicals" as they reject Apostolic succession, but they are Trinitarians

Unitarians aren't really even Christians as they reject the basic tenets of Christianity and some seem akin to Judaism, while others are so wishy-washy, it's possible to just call them "peace dude" types. Mormons are a different matter.

Unitarians believe in, at most, one God
