By the sea-
When you first began researching yourself, did you find yourself being an apologist for JW beliefs? I did. But the more I researched, the more I realized that the doctrines/assertions didn't add up. If you think you have the 1919 stuff down pat and can explain your doubts using Society literature, you might challenge your husband to become the Watchtower apologist and disprove your allegations. I truly think giving HIM something to research is the best way. You can ask him to get back to you next weekend with what he's found.
Good luck!
