Valis,
Do you feel better having it all out?
It's kind of like surgery. If you have a cancer sometimes you need to have it removed. Now your position is clear. There is little turning back. I took your route with my jw family. They would not listen to me for over a year. Finally I wrote a letter expressing my feelings and my view of the jw's. Maybe I should post it. My family then started attacking and I stood my ground; Like you. But after one round I saw it as futile. I really don't like these people. They are shallow and backbiters. I have talked to the rest of the family and they said that my inlaws were like this even before the cult. There they are among others just like them. They have no respect for anyone and demand it from everyone. I have left them to themselves, even in my mind.
If you want a relationship with your Father then read Hassen and start using stratagy. You can have a relationship if it is worth the time, heartache, and stress to you. No one is unsaveable. But for me I focus on those who have yet to convert, the ones who do not know the true nature of this sect. And those who are or, desire to be in control of their actions and want to be responsible for themselves. Real people are cool. You can really trust them. You can freely love them and not worry.
There are all types of people who will not think for themselves. In and out of someones family. Remember to choose your battles. Don't let them choose them for you. My email is open for you if you want to talk.
For what it is worth I respect you for standing up for yourself. For being honest about your feelings. It takes balls to do that.
