Decades , good grief .
I myself probably only a year or two.
This religious organization was made up by men who were both ignorant and consumed into their own self empowerment which they unitized through the literature they published, which helped to establish and sustain that appealing power and control.
In the engaging process to build that power and control, they lied a lot and deceived a lot, in their continuing agenda to proliferate their published works.
Staying with this organization is belittling your own intelligence and personal integrity as an individual.
To assume that Jehovah would approve of commercialized false prophets belittles god as well and is directly disobedient to him and his son, according to bible scripture.
