For what it's worth, these are the interesting topics that I'm not sure most people know:
1. On the conscientious objector matter, no individual decided for himself that he was a conscientious objector. This "conscience" was injected into them with WT propaganda. I was a young dub (but female) during the Vietnam war. I was told by several young brothers that they could not accept a position in a hospital in lieu of military service because that would be considered "compromise." Again, the brothers did not themselves necessarily see it as "compromise." A young man had to be sentenced to public service work by a judge before that would be considered an acceptable way to avoid military service.
2. "Worldly" people have told me that JW's were harmless crackpots. I remind them of ruined lives of people who forego education or make a misstep which leads to being cut off from their own families.
3. Medical quackery is BIG in the borg. Vaccinations used to be forbidden, dubs were told not to chew gum, not to use aluminum cookware and similar crazy pseudo-scientific claptrap. The biggest tragedy of all is that dubs refuse blood transfusions that could save their lives because of what they are told is meant by scriptures not at all related to medical procedures.
You probably have already included all of these items in your book. Best wishes with publication.
