I lurked on this site for about 7 years before taking definitive actions. However, I must admit that what truly did it was the simple question from Raymond Franz's book: Who is the bad christian, the one who questions a teaching, or the one that throws out and calls names his brother for questioning him on anything at all?
It was very simple, but enough for me to understand that what truly matters is love, not details. With the WT, its the other way around.
