Nice write up. That must have taken you a lot of time. Thank you for putting effort into that.
When I've discussed this subject with a dub they answer from an emotional place and not a logical one. The Good News to them isn't the Good News that Paul discusses, rather it's the fact that soon God will destroy the wicked and the earth will become a paradise. Is that the official Good News that JWs proclaim? No. Your write up shows that. Plus the umpteen other articles that tell JWs that seving God for life in paradise earth is wrong.
The dubs don't listen - not even to 'mother'. The WT has learned not to be too specific in things like this.
