It is striking that there are a lot of people in the world who are opposed to those who worship Jehovah as their only true God. The vast majority of those anti-Jehovah people come from extreme right-wing groups and fundamentalist or very conservative Christian groups.
In the history of Christendom we see many churches which started of as so called cults or so called heretic movements, though many years later they sometimes outgrew their original group and/or became one of the many main churches. Therefore one should be very careful by damning a group or calling ti a cult or sect, when there is not really anything what qualifies it to become called a sect or cult.
Before calling a church or religious group a "cult" or "sect" one should seriously examine and clarify what one means with those qualifications.
