People in these congregations were always forced to be in one or the other based on where they lived. And when you force people together there is resentment and backbiting. People dont choose to go to CHURCHES they dont like and sit with parishioners they dont get along with but the JWs have to. I hardly like ANY of the people in at least two of the congregations I was in. And you then have to deal with them 5 hours a week and for every service time? And all the pot lucks? Ugh...blech.
Sometimes they break up these disfunctional congregations and feed the parts to other congregations in lieu of lining them all up and shooting them and getting the teal and purple paisley carpeting bloody.
