I understand what you're going through. I just told my best friend I was having doubts,and now,she doesn't even respond to e-mails.
Then,it's easy to question yourself. It's a scary situation,turning your back on what you've always now. And there doesn't seem to be a middle ground for the Witnesses. You're either with them or against them.
But, it's true,if you want to stay under the radar and not be d'fd,you have to just not comment. It's hard,because you hear so many ludicrous comments from Witnesses. But,anymore,to keep peace,I just don't say anything.
Plus,I've gradually deleted all Witnesses I know on my facebook. And I won't be accepting any friend requests from them either. If they were good dubs they wouldn't be on facebook anyway.lol.
