I've enjoyed reading your post, since I also walked away from a similar experience.
You surely exemplified courage to allow your children to pursue some of the things that are not harmful, but could benefit them in their future, knowing that it would meet some resistance from the congregation. Afterall, you're not serving as an Elder anymore, why should you and your family be under the same microscope?
Those brothers who had met with you are probably under pressure to do so, what a sad thing to see, when the Jan 1 Watchtower 2007 tells us to widen out in love. How can such ones read/write this material and get it so wrong in it's application?
Hang in there, and doing so will demonstrate to your family, who you show is the most important to you, and not some misconception that some over righteous ones may try to pressure you into.
Reading the Watchtower is not what it's cracked up to be. This is just the silling games that the ORG tries to use in motivating the congregations to be on board. You have shown that you choose not to sell your childrens happiness in exchange for reading some paragraphs in an audience that wants the study to finish fast.
