My brother, a long-time elder and now a circuit overseer, stopped associating with me almost 20 years ago. I've never been disfellowshipped or reproved; neither have I diassociated myself. His reasoning is that I'm an apostate because I left the religion (and therefore god, in his mind) and because I don't believe the JW teachings. I tried to reason with him about the fact that I got baptized as a minor, and that if I'd known then what I know now, I never would have been baptized. It doesn't matter to him. I left the religion; I'm an apostate. Very black and white. He's convinced my sister to take the same stand.
The funny thing is that he made this decision long before I married Alan, the arch-apostate. Now he's really scared to death of me!
