Lisa,
My personal opinion is that difference in access to privileged information within the organization aside, the differences may be related to communication style. Something I've read several times before is that men and women use communication for different purposes. Namely, men use communication and conversation to jockey for position and to establish rank while women use it for building and nurturing relationships. This might also explain why you have men who dominate meetings and are quite aggressive at work coming home and having very little to say to their wives and families. Women, on the other hand, are more likely to go home and take the larger part in communicating within the family.
I agree with you that you should try a different tact with your family. Reading many of the threads from new posters I have come to see that most left Watchtower following some disillusionment or out of weakness. Even the society knows this, often encouraging and providing scripts specifically for situations like death of a loved one and disillusionment with the state of the world. We would do well to follow their example.
I tried speaking with my sister at Christmastime about the molestation and United Nations issue. Now she has been inactive for a couple of years and had just sort of bragged about having a string of christmas lights hanging on her window and allowing her kids to celebrate birthdays. Her speech was also liberally peppered with curse words which she uttered without apology. However, when I launched into my attack on the society, she became a staunch advocate for watchtower. I couldn't believe the transformation! Since then I have learned that frontal attacks do nothing but strengthen their resolve for they are well defended.
Anyway, I admire your aim and the work that all of the men have put into dethroning the watchtower, but I also recognize that the women do an equally outstanding job of attacking the watchtower by subverting the faith of dubs. Their way of doing things is just not so in-your-face.
