They have been, from their inception, a sect that was considered different from mainstream Christianity. They LOVED being different. They bragged about being "persecuted."
Their health beliefs were quite often weird, to put it mildly.
They seemed to really know their Bible but in fact, they play scriptural gymnastics to make a defense of their odd views.
They once were "Bible Students" and now, most couldn't defend a belief if their life depended on it.
Pretty much, nothing has changed. They still have been talking about us "living in the time of the end", and no doubt they will still be spouting their nonsense for "generations" to come---unless, of course, they change their view of that (again) too.
