Randy,
That was a great letter. He sounds sincere and his side of the "assault" story is believable. Too bad he does sound like a bit of a whiner. He's giving a lot of power to the JW wife. He'll just keep losing if he doesn't try a bit harder.
Since he asked about "any redeeming JW qualities" perhaps he's ready for some witnessing of his own. A father has a right to speak in his home doesn't he? If I were him, I'd say that the kids can study all they want and be baptized as long as I, the Dad, have a chance to study 1 hour a week with them. He should take poignant ideas from the Internet that use JWs own books to debunk themselves. He should preface his study with: "If I'm doing the right thing by studying with you, then I should expect persecution for doing this, right? Even if that persecution comes from one of Jehovah's Witnesses (pre-implicating their mother), we shouldn't give up, right?" Turn the tables before it's too late!
