@MartinTheFirst: It is a cult but I don't expect you to see it as you're currently in one. Most cult members don't believe they are in a cult until they get out.
The full definition of cult:
cult (kŭlt)
n.
1.
a. A religion or religious sect generally considered to be extremist or false, with its followers often living in an unconventional manner under the guidance of an authoritarian, charismatic leader.
I would say the watchtower society and the governing body fit this bill
b. The followers of such a religion or sect.
2. A system or community of religious worship and ritual.
the kingdom hall is a community and you get together to worship. Having been to kingdom hall before I can tell you are either delusional or lying when you say it isn't a ritual.
3. The formal means of expressing religious reverence; religious ceremony and ritual.
4. A usually nonscientific method or regimen claimed by its originator to have exclusive or exceptional power in curing a particular disease.
5.
a. Obsessive, especially faddish, devotion to or veneration for a person, principle, or thing.
In my experience it is insane how obsessed JW'S are with their beliefs.
b. The object of such devotion.
6. An exclusive group of persons sharing an esoteric, usually artistic or intellectual interest.
