Yup.
You and the JWs, Gnostics, etc.
Very good company indeed.
Not to mention Lutherans, Calvanists, Anabaptists, Baptists, both the Roman Catholic AND the Eastern Orthodox Church.
Be fair here, all of these have been called heretical.
Don't forget the Protestants, Roman Catholics, Eastern Orthodox, and so on. Be sure to include your own church, denomination, or sect—odds are, someone somewhere considers you a heretic.
The point is, heretic has little objective meaning anymore (if it ever did). The word is intended more to defame than to describe; but it has lost its sting now that the self-described "orthodox" no longer burn heretics at the stake.
