I want to know the answer to the following question:
What do Orthodox jewish groups characterize non-orthodox form of Judiasm as?
All the background I'm provided with is that "The Orthodox Jewish movements consider all non-Orthodox Jewish movements to be unacceptable deviations from authentic Judaism; both because of other denominations' doubt concerning the verbal revelation of Written and Oral Torah, and because of their rejection of Halakhic precedent as binding.". Is that enough to answer the question?
Answer: no
