Gossip was one of a very short list that convinced me that JW's were full of shit. I bought into the whole 'we are better than everyone else in the world' bs. Once I started getting more involved in congregation matters I realized it was just one giant rumor mill. I saw people get DF'd off of nothing more than rumors. This is when I became loud and confrontational right in the KH as often as I could. Of course the Elders had to talk to me about my 'bad attitude'. I told them with our 'rumors are bad talks' every 3 weeks I thought it prudent to make sure to tell a person to their face exactly what I thought so as not to cause any confusion.
Now, I have no problem telling a person what I think so long as I feel they are worth the effort. In cases of JW's, most of the time they are not worth the time.
